Subject [jira] [Commented] (HIVE-4851) Fix flaky tests
Date Mon, 22 Jul 2013 17:44:48 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4851?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13715437#comment-13715437

Yin Huai commented on HIVE-4851:
--------------------------------

oops, I somehow missed it...

In bucketmapjoin6, there are 10 buckets for every input table. So, we will have 10 mappers
to do SMB join. Will the number of buckets be the problem?

> I see the following tests fail quite often:
> * TestNegativeMinimrCliDriver.testNegativeCliDriver_mapreduce_stack_trace_hadoop20
> * TestOrcHCatLoader.testReadDataBasic
> * TestMinimrCliDriver.testCliDriver_bucketmpjoin6
> * TestNotificationListener.testAMQListener
> This one is less often, but still fails randomly:
> * TestMinimrCliDriver.testCliDriver_bucket4
> * TestHCatHiveCompatibility.testUnpartedReadWrite
> * TestHCatLoader.testReadPartitionedBasic
> * TestMinimrCliDriver.testCliDriver_bucketizedhiveinputformat
