[jira] Issue Comment Edited: (PIG-571) pigserver methods do not
throw error or return error code when an error occurs
[ https://issues.apache.org/jira/browse/PIG-571?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12664657#action_12664657 ]

-------------------------------------------------------------------
In the current implementation, Pig displays the errors including the stack trace but does not throw an exception. There are two problems in the existing code:
1. Hadoop returns status as String instead of serialized objects
2. Pig does not throw an exception on failures with the appropriate details.
As part of the error handling feature, Pig will handle point 2 in the third milestone(PIG-590) and request Hadoop to support status reporting via objects and not just Strings.

> I do PigServer.registerQuery("store ..."), and the query fails. Pig prints a bunch of stack traces but does not throw an error back to the caller. This is a major problem because my client needs to know whether the Pig command succeeded or failed.
> I saw this problem with registerQuery() ... the same problem may arise with other PigServer methods as well, such as store(), copy(), etc. -- not sure.
