Subject [jira] [Commented] (IGNITE-9429) GridCacheReplicatedDataStructuresFailoverSelfTest#testAtomicSequenceConstantTopologyChange is flaky
Date Fri, 07 Sep 2018 19:04:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-9429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16607528#comment-16607528

Pavel Pereslegin commented on IGNITE-9429:
------------------------------------------

[~agoncharuk], seems we can miss some bugs with catching
IllegalStateException for all datastructures. I see only one problem
in this test - {{G.allGrids()}} returns unordered list now, so we should
change:
{code:java}
if (circular)
    stopGrid(G.allGrids().get(0).configuration().getIgniteInstanceName());
{code}
to
{code:java}
if (circular)
    stopGrid(i);
{code}

This will fix flaky failures and preserves the idea of "circular" node stopping.

> Test fails with various exception, I see several issues:
> 1) Atomic structure is accessed during a node stop, which leads to NodeStoppingException
(should be ignored)
> 2) Same race which leads to IllegalStateException: node is stopped
> 3) Invalid atomic integer increment which rarely leads to "Ignite instance with the same
name has already been started" exception
