Ivan Bessonov created IGNITE-11574: -------------------------------------- Summary: Exchange on NodeLeft event hangs when cluster is in transition state Key: IGNITE-11574 URL: https://issues.apache.org/jira/browse/IGNITE-11574 Project: Ignite Issue Type: Bug Reporter: Ivan Bessonov Assignee: Ivan Bessonov Attachments: ExchangeDeadlockTest.java
The problem is in this code (GridCachePartitionExchangeManager#start0) : {code:java} if (cache.state().transition()) { if (log.isDebugEnabled()) log.debug("Adding pending event: " + evt); pendingEvts.add(new PendingDiscoveryEvent(evt, cache)); }{code} Problem occurs when "setBaseline" and "nodeLeft" events happen simultaneously (+ some undetermined conditions). "nodeLeft" provokes exchange, and while that exchange isn't finished "setBaseline" is invoked. This moves cluster into a transition state and "CacheAffinityChangeMessage" from the exchange cannot be processed properly. At the same time "setBaseline" cannot be completed before the exchange, so we have a deadlock. Reproducer attached. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
