--------------------------------------
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}}?
> Add conf. property hive.exec.show.job.failure.debug.info to enable/disable
> displaying link to the task with most failures

>
> 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.
