-----------------------------------

             Summary: Some tests derived from GridCacheAbstractRemoveFailureTest class fail
sometimes
                 Key: IGNITE-1233
                 URL: https://issues.apache.org/jira/browse/IGNITE-1233
             Project: Ignite
          Issue Type: Bug
          Components: cache
            Reporter: Andrey Gura
            Assignee: Andrey Gura


Some tests derived from {{GridCacheAbstractRemoveFailureTest}} class fail sometimes. Most
stable failures thre are in the following tests (accordingly to failure probability):

  * {{org.apache.ignite.internal.processors.cache.distributed.dht.GridCacheDhtClientRemoveFailureTest}}
  * {{org.apache.ignite.internal.processors.cache.distributed.near.GridCacheNearRemoveFailureTest}}
  * {{org.apache.ignite.internal.processors.cache.distributed.dht.GridCacheDhtRemoveFailureTest}}

This problem was found during fixing IGNITE-1175 ticket. It seams that  there is concurrency
issue that leads to failures.

Log snippet:

{noformat}
[20:14:22,624][ERROR][test-runner][root] Unexpected cache data [exp=7923=GridTuple [val=null],
actual=55, nodePrimary=false, nodeBackup=false, nodeIdx0, nodeId=001ba37c-455a-4254-81b9-bd4e20cb2000]
[20:14:23,078][ERROR][test-runner][root] Unexpected cache data [exp=7923=GridTuple [val=null],
actual=55, nodePrimary=true, nodeBackup=false, nodeIdx1, nodeId=1089c623-6330-4b6a-9bd7-b5217b63a001]
[20:14:23,322][ERROR][test-runner][root] Unexpected cache data [exp=7923=GridTuple [val=null],

{noformat}

Of course the nodes list depends on current topology and can varying from 1 to 3 for this
tests.
