Summary: 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-1.5 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) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
