Subject [jira] [Commented] (HBASE-7350) Flakey tests make CI unreliable
Date Fri, 14 Dec 2012 00:00:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13531663#comment-13531663
] 

Nick Dimiduk commented on HBASE-7350:
-------------------------------------

The warning is more for information gathering -- are we frequently abandoning and killing
processes? I see no reason not to commit it permanently.

Reducing the thread count is an experiment to see if our more strenuous integration tests
pass more consistently when run with less concurrency. I don't actually know what tests are
included in the "secondPart," hence the request for review from others more knowledgeable.

> Most PreCommit and PostCommit builds are failing these days. Keeping an eye on usual
suspects reveals them to be mostly longer-running tests. Either the tests need to me made
more rigorous or the erroneous Jenkins configuration needs addressed.
> The usual suspects:
> - org.apache.hadoop.hbase.client.TestMultiParallel
> - org.apache.hadoop.hbase.TestDrainingServer
> - org.apache.hadoop.hbase.regionserver.TestSplitTransaction
> - org.apache.hadoop.hbase.client.TestMultiParallel.testFlushCommitsNoAbort
> - org.apache.hadoop.hbase.replication.TestReplication
> - org.apache.hadoop.hbase.util.TestHBaseFsck
