[jira] [Commented] (PIG-3994) Implement getting backend exception for Tez

    [ https://issues.apache.org/jira/browse/PIG-3994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14488117#comment-14488117 ] 

Rohini Palaniswamy commented on PIG-3994:
-----------------------------------------

Please have that in a try catch block. First try to do Launcher.getExceptionFromString() which tries to actually construct a stack trace and if that encounters errors (you might have to do some additional string manipulation as well), then wrap whole diagnostics in an exception in the catch block.
