[jira] [Commented] (PIG-4418) NullPointerException in JVMReuseImpl
[ https://issues.apache.org/jira/browse/PIG-4418?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14487155#comment-14487155 ]
Carlos Balduz commented on PIG-4418:
------------------------------------
I'm having the same problem, although I cannot reproduce it either. It happens when I try to make a self join of a huge table... However after the failed task attempt, the job continues.
