Tom Pantelis [Wed, 27 Jul 2016 19:52:53 +0000 (15:52 -0400)]
Bug 5504: Add PreLeader raft state

The following scenario can result in a "store tree and candidate base
differ" IllegalStateException on commit:

A follower receives a replicate and adds it to the log, say at index 1,
but the leader transfers or dies before committing and applying it to the
state. The follower becomes leader and when the next tx is applied, log
index 2, it has to first apply all log entries from the previous term that
hadn't been committed yet, in this case index 1. Since we got consensus for
index 2 that means index 1 has also been replicated to a majority. Therefore
ApplyState is sent for index 1 and then index 2. However index 1 is applied
as a "foreign" candidate while index 2 is in the pre-commit state. When
index 2 is applied the commit fails.

To prevent this scenario, we introduce a new raft state, PreLeader,
which is transitioned to from Candidate if there are uncommitted
entries, ie commit index < last log index. The PreLeader state performs all
the duties of Leader with the added behavior of attempting to commit all
uncommitted entries from the previous leader's term. Raft does not allow a
leader to commit entries from a previous term by simply counting replicas -
only entries from the leader's current term can be committed (§5.4.2). Rather
then waiting for a client interaction to commit a new entry, the PreLeader
state immediately appends a no-op entry (NoopPayload) to the log with the
leader's current term. Once the no-op entry is committed, all prior entries
are committed indirectly. Once all entries are committed, ie commitIndex matches
the last log index, it switches to the normal Leader state.

The PreLeader state is considered an inactive leader state and thus
client transactions are delayed until it transitions to Leader.

Bug 6278: Copy karaf-parent from controller to odlparent

As discussed in the MD-SAL call, there is an architectural need to move
karaf-parent from the controller project to the odlparent project.  This
is particularly useful for karaf upgrades, since right now a bump in karaf
version within odlparent requires a rebuild of controller to reflect the
change in karaf-parent, and our build jobs are not set up to support such
a process.

The move process will be handled in multiple steps:

1) Copy karaf-parent, karaf-branding and opendaylight-karaf-resources to
odlparent.  All three of these should belong in odlparent.  All three must
be moved since karaf-parent depends on the latter two artifacts.  Since
controller depends on odlparent (and not the other way around), they must
be moved upstream to odlparent.

2) Have controller's karaf-parent derive from odlparent's karaf-parent.
This preserves the ability for downstream consumers to derive from the
controller karaf-parent in the interim, while allowing changes to odlparent's
karaf-parent to be recognized since controller does not need to be rebuilt.
[THIS PATCH]

This also involves removing karaf-branding and opendaylight-karaf-resources
from the controller project, since they are no longer needed.  There are two
consumers that need to be patched:
lispflowmapping: https://git.opendaylight.org/gerrit/42647
vtn: https://git.opendaylight.org/gerrit/42648

3) Change all downstream projects to utilize odlparent's karaf-parent.  This
is future work and will be done in several patches.

4) Remove controller's karaf-parent once we feel all downstream consumers
are using the odlparent's karaf-parent.

anywhere from 40 s to 3 min, depending on timing. What happens is that
the first node goes to Candidate first but it's RequestVote is rejected
by the seconds node. Shortly after the seconds node goes to Candidate -
the term is higher than the first which causes the first node to go back
to Follower. However it doesn't respond to the RequestVote. Then the
first node goes to Candidate and the cycle repeats. Eventually, due to
the election variance, the seconds node times out first and the second
node process the RequestVote and grants it. But it can take more than 10
cycles.

We can improve the convergence by allowing a Candidate to process and
respond to RequestVote when the sender's term is greater. It still
transitions to Follower as per the raft rules. The raft paper does not
say whether or not a Candidate can/should process a RequestVote in this
case but it seems to make sense. With this change, the first RequestVote
sent by the second node is granted and it converges quickly.

3 years agoAlleviate premature elections in followers 64/42564/7

Alleviate premature elections in followers

If a follower actor is busy or some non-leader messages take longer to process,
leader messages may get backed up enough to cause the election timer to
expire, thereby resulting in an unwanted election and leader disruption. To
alleviate this scenario, I added a Stopwatch to keep the last time a leader
message was received, ie when a leader message is received it restarts
the Stopwatch. When ElectionTimeout is received, it checks if the
elapsed time of the Stopwatch has exceeded the election timeout
interval. Therefore if leader messages were occurring during the
election timeout interval but were delayed, they will be processed
before the ElectionTimeout message and restart the Stopwatch such that the
elapsed time will/should be less than the election timeout interval by the
time ElectionTimeout is received (unless the last leader message happened to
take longer than the election timeout interval).

There are cases where ElectionTimeout is manually sent to force an
election timeout (eg during leadership transfer). In these cases we
don't want to check the Stopwatch so I added an explicit TimeoutNow
message to distinguish the 2 messages.

BUG-5280: centralize ShardSnapshot operations

Current shard snapshotting mechanism does not allow for evolution
of the snapshot contents and contains only the root node. Also
the serialization and deserialization operations are scattered
in multiple places, making coordinated changes a bit troublesome.

This patch introduces a versioned snapshot abstraction and moves
serdes operations into a single place. A new serialization format
is introduced, which holds the root node and some additional
metadata. No concrete metadata is defined in this patch, but this
will be used to transfer frontend protocol state from shard leader
to shard follower.

It also moves the act of creating a snapshot into ShardDataTree
and creates a dedicated actor to handle the snapshotting task,
which is used for all snapshot requests for a particular Shard.
Also makes the actor message internal to the ShardSnapshotActor,
providing a convenience method to create and dispatch it.

BindingToNormalizedNodeCodec class instead of an interface. Therefore
the global static instance was created via blueprint and advertised via

return an instance of BindingToNormalizedNodeCodec in order to provide
the binding-dom-mapping-service so obtaining the blueprint advertised OSGi
service via its interfaces and casting to BindingToNormalizedNodeCodec
failed b/c Aries creates a service proxy which loses the fact that it's a
BindingToNormalizedNodeCodec instance.

However the global BindingToNormalizedNodeCodec instance is not clean and
is problematic for supporting blueprint container restarts. Aries supports
concrete class proxies so I added an additional service export for the
BindingToNormalizedNodeCodec class in the binding-broker blueprint XML.
In addition, the blueprint XML now calls a new method, "newInstance", on the
BindingToNormalizedNodeCodecFactory to create a new instance and calls a
new method, "registerInstance", to register it with the SchemaService. The
returned ListenerRegistration instance is put into a bean so it can be
closed on destroy. The RuntimeMappingModule now obtains the
BindingToNormalizedNodeCodec instance from the OSGi registry as the other
blueprint-bridged CSS modules do. This eliminates the need for the global

3 years agoForce install snapshot when follower log is ahead 35/41535/2
Tom Pantelis [Fri, 1 Jul 2016 04:25:17 +0000 (00:25 -0400)]
Force install snapshot when follower log is ahead

It's possible for a follower's log to actually be ahead of the leader's log.
Normally this doesn't happen in raft as a node cannot become leader if its
log is behind another's. However, the non-voting semantics deviate a bit
from raft. Only voting members participate in elections and can become
leader so it's possible for a non-voting follower to be ahead of the leader.
This can happen if persistence is disabled and all voting members are
restarted. In this case, the voting leader will start out with an empty log
however the non-voting followers still retain the previous data in memory.
On the first AppendEntries, the non-voting follower returns a successful
reply b/c the prevLogIndex sent by the leader is -1 and thus the integrity
checks pass. However the follower's returned lastLogIndex may be higher in
which case we want to reset the follower by installing a snapshot.
Therefore I added a check in AbstractLeader#handeAppendEntriesReply if
the reply lastLogIndex > leader's last index.

Since the initial AppendEntries is sent immediately by the leader,
normally the follower will reply and this change works. However if a
follower happens to be disconnected and doesn't reply for some time, the
leader can still progress with new commits. If the leader has enough
commits such that its lastIndex matches or exceeds the lagging
non-voting follower, this check doesn't work. In this case, the
follower's integrity checks will fail since the leader's prevLogTerm
will differ. On reply the leader will start decrementing the follower's
nextIndex in an attempt to find where the logs match. During this
process the leader may trim its log via replicatedToAllIndex in which
case the follower's nextIndex may no longer be in the leader's log and
the leader will install a snapshot.

However if other nodes are down and prevent the log trimming then the
follower's nextIndex may be in the log until it eventually decrements to
0. The follower's integrity checks will pass in this case since the
leader's prevLogIndex will be -1. The follower will then attempt to add
the leader's log entries to its log. It first loops the log entries in
the AppendEntries with the intent of skipping matching entries in its
log (ie index and term the same) and stopping when it finds an entry
that doesn;t exist or finds one whose term doesn't match, in which case
it removes the entries beginning at this index. However I found some
issue in this code. First it was calling get on the getReplicatedLog
which doesn't take into account that the index may be part of the prior
snaphot and not actually in the log. I changed this check to
isLogEntryPresent which takes into account the snapshot. Second, if it
hits a conflicting entry it tries to remove it from the log. However,
as before, it may be in the snapshot and not in the log in which case
nothing gets removed. To alleviate this, I modified removeFromAndPersist
to return a boolean - false meaning it didn't find the index. In this
case I changed it to send back a reply to force a snapshot.

I added several tests in a new class NonVotingFollowerIntegrationTest
that runs thru various scenarios to cover the cases described above.

While testing I ran into some orthoganl issues that I also fixed.

- if a leader has only non-voting followers, on replicate, it should
  immediately commit and apply to state as it does when there's no
  followers since it doesn't need consensus from non-voting followers.
  So I added a method anyVotingPeers to RaftActorContext to handle this
  case.

- When calculating the prevLogIndex and prevLogTerm for the
  AppendEntries message, it calls get on the getReplicatedLog
  which doesn't take into account that the index may be the snaphot
  index/term. Follower does this check prevLogIndex/prevLogTerm so
  the leader should as well.

4 years agoMove GlobalBundleScanningSchemaServiceImpl to its own bundle 58/40458/4
Tom Pantelis [Thu, 16 Jun 2016 01:04:02 +0000 (21:04 -0400)]
Move GlobalBundleScanningSchemaServiceImpl to its own bundle

Moved the GlobalBundleScanningSchemaServiceImpl and the associated
BundleActivator, SchemaServiceActivator, from sal-dom-broker to a new
bundle sal-schema-service.

A couple reasons for this. One is to break the circular service imports
between sal-dom-broker and sal-distributed-datastore, where
sal-distributed-datastore imports the SchemaService from sal-dom-broker
and sal-dom-broker imports the DOMDataBroker from
sal-distributed-datastore. The result of this was that if the
sal-dom-broker blueprint container was restarted, it would also cause
the sal-distributed-datastore container to restart, which isn't
necessary/desirable.

The other reason is that apps can register a SchemaContextListener as an
OSGi service which is picked up by the
GlobalBundleScanningSchemaServiceImpl. In terms of service usage this
makes sal-dom-broker a dependency of the app bundle so if the app
container restarts, it also restarts sal-dom-broker,
sal-distributed-datastore etc which isn't desirable.

So moving the GlobalBundleScanningSchemaServiceImpl to its own bundle
alleviates both issues.
