[jira] [Commented] (PIG-2543) PigStats.isSuccessful returns false if embedded pig script has sh commands

["Daniel Dai (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-2543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13224083#comment-13224083 ] 

Daniel Dai commented on PIG-2543:
---------------------------------

The current design of PigStats is all based on mapreduce jobs. It does not have the position for "sh" commands. I propose to adding a flag auxiliaryErrors to PigStats to track non mapreduce errors, and isSuccessful returns true only if all mapreduce job success and no auxiliaryErrors.
