Assignee: (was: Semen Boikov)
> Async cache operations in IGFS may cause deadlock related to topology update
> ----------------------------------------------------------------------------

> Key: IGNITE-1304
> URL: https://issues.apache.org/jira/browse/IGNITE-1304
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: ignite-1.4
> Reporter: Ivan Veselovsky
> Fix For: ignite-1.4
>
> Attachments: deadlock-1304.txt
>
>
> In an IGFS test we observe a deadlock situation related to cluster topology
> update (full thread dump is attached).
> The problem is that several threads are waiting for the topology update, at
> the same time holding the read lock of the topology version update:
> Thread #1:
>
> GridAffinityAssignmentCache.awaitTopologyVersion(GridAffinityAssignmentCache.java:450)
> ....
>
> GridNearOptimisticTxPrepareFuture.prepareOnTopology(GridNearOptimisticTxPrepareFuture.java:280)
> At the same time another thread, that wants to update the topology version,
> cannot do that because it needs the write lock of the topology update:
> Thread #2:
> at
> java.util.concurrent.locks.ReentrantReadWriteLock$WriteLock.lock(ReentrantReadWriteLock.java:945)
> at
> o.a.i.i.processors.cache.distributed.dht.GridDhtPartitionTopologyImpl.updateTopologyVersion(GridDhtPartitionTopologyImpl.java:190)
