Subject [jira] Commented: (HIVE-1578) Add conf. property hive.exec.show.job.failure.debug.info to enable/disable displaying link to the task with most failures
Date Sat, 21 Aug 2010 00:55:16 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12900948#action_12900948

Carl Steinbach commented on HIVE-1578:
--------------------------------------

It would probably also be a good idea to add some INFO level logging statements to the loop
in showJobDebugFailInfo() so that the user can roughy gauge the rate of progress.

> 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.
