[jira] [Commented] (IGNITE-647) org.apache.ignite.IgniteCacheAffinitySelfTest.testAffinity() hangs

["Semen Boikov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-647?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15069394#comment-15069394 ] 

Semen Boikov commented on IGNITE-647:
-------------------------------------

There is one more race here:
- node 1 starts, exchange is finished
- node 2 starts, exchange is finished
- node 2 starts cache with fair affinity function, starts exchange and sends GridDhtAffinityAssignmentRequest to node1. At this point node1 started exchange process, but did start cache yet and did not register required message handler so message will be ignored.

So any dynamic cache start with fair affinity initiated from non-oldest node can easily hang.
