--------------------------------------

Hi Paul, before calling showJobDebugFailInfo() can you please print out a message telling the user that you're going to do this, that it may take a long time to complete, and that this feature can be disabled by setting the conf property {{hive.exec.show.job.failure.debug.info}}?

> If a job fails, Hive currently displays a link to the task with the most number of failures for easy access to the error logs. However, generating the link may require many RPC's to get all the task completion events, adding a delay of up to 30 minutes. This patch adds a configuration variable to control whether the link is generated. Turning off this feature would also disable automatic debugging tips generated by heuristics reading from the error logs.
