Evgeny Stanilovsky updated IGNITE-20489:
----------------------------------------
Fix Version/s: 3.2
(was: 3.1)
> Tests that transfer leadership must make sure it doesn't change spontaneously
> -----------------------------------------------------------------------------
>
> Key: IGNITE-20489
> URL: https://issues.apache.org/jira/browse/IGNITE-20489
> Project: Ignite
> Issue Type: Bug
> Reporter: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3
> Fix For: 3.2
>
>
> At least ItSchemaSyncAndReplicationTest and ItTableRaftSnapshotsTest transfer
> leadership to chosen nodes in a cluster. If the leadership gets transferred
> from the node chosen by the test (this might happen due to a GC pause, for
> example), the test might fail.
> We could forbid a node to request votes for becoming a leader by blocking
> RequestVoteRequests either on the network level (substituting the response
> with a fake response with granted=false) or on the server (by substituting
> RequestVoteRequestProcessor).
> We should also make sure that Primary Replica remains the same as the Leader
> for the whole duration of test. Otherwise,
> ItTableRaftSnapshotsTest#txSemanticsIsMaintained() might route the commit
> request to a node that has just been stopped causing an (irrelevant) test
> failure.
