Subject [jira] [Commented] (IGNITE-1233) Some tests derived from GridCacheAbstractRemoveFailureTest class fail sometimes
Date Thu, 13 Aug 2015 20:50:46 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-1233?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14695917#comment-14695917
] 

Andrey Gura commented on IGNITE-1233:
-------------------------------------

During debug I found out that some entries is not removed from {{GridCAcheAdapter.map}} on
some/all nodes. In this cases map contains entries with old values. I'll try find the cause
of this behavior.

> 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.

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