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?

> TestNegativeMinimrCliDriver.testNegativeCliDriver_mapreduce_stack_trace_hadoop20
> * TestOrcHCatLoader.testReadDataBasic
> * TestMinimrCliDriver.testCliDriver_bucketmpjoin6
> * TestNotificationListener.testAMQListener
> This one is less often, but still fails randomly:

> * TestHCatHiveCompatibility.testUnpartedReadWrite
> * TestHCatLoader.testReadPartitionedBasic
> * TestMinimrCliDriver.testCliDriver_bucketizedhiveinputformat
