[jira] [Commented] (HIVE-6588) Unit test failures with hadoop-2

    [ https://issues.apache.org/jira/browse/HIVE-6588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13932624#comment-13932624 ] 

Szehon Ho commented on HIVE-6588:
---------------------------------

Just wanted to share my experience, a lot of these are caused by MAPREDUCE-434 which is in hadoop 2.3.0, hive MR jobs in test env had been running only one reducer in local mode, now suddenly there are more.  

I think the majority of these can be fixed by adding a group-by, or having a different version of the test for hadoop1,2 versions for others, like those asserting number of buckets.  Will try to fix some if I get some cycles.
