[jira] [Commented] (OOZIE-2794) Hive and Pig tests failing when multiple pre-commit jobs are running

["Andras Piros (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-2794?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15946922#comment-15946922 ] 

Andras Piros commented on OOZIE-2794:
-------------------------------------

It's also suspected that {{bin/test-patch-11-findbugs-diff}} may also fail sometimes because multiple pre-commit jobs are running on the same Jenkins slave at the same time:
