Subject [jira] [Commented] (IGNITE-9654) Test testJoinQueryUnstableTopology is flaky in master
Date Sat, 22 Sep 2018 14:29:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-9654?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16624693#comment-16624693
] 

Amelchev Nikita commented on IGNITE-9654:
-----------------------------------------

I have fixed the main problem in the test that appeared after merge IGNITE-8158.

The reason was in the grid restart future that interrupted by timeout. _awaitTopologyChange()_
invocation in the method _GridAbstractTest#stopGrid_ throws _InterruptedException_ and setting
_stopGridErr_ flag. It throws _RuntimeException("Not all Ignite instances has been stopped")_
on tear down.

But the test is still flaky(low probability). The reason is described in IGNITE-7766 and still
unsolved. I have added an error message in the test method for clarity. [TC mass runs tests|https://ci.ignite.apache.org/viewType.html?buildTypeId=IgniteTests24Java8_Queries1&branch_IgniteTests24Java8=pull%2F4797%2Fhead&tab=buildTypeStatusDiv].
