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 Thu, 26 Aug 2010 08:28:54 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12902774#action_12902774

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

@Paul: I understand that showing % complete is not possible, but I do think it would help
to log a message as each task completion event is retrieved so that the user sees progress
is being made. The most frustrating thing about the current behavior is that the CLI appears
to just freeze leaving the user with no idea what's going on.

> 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.
