Subject [jira] Commented: (HIVE-713) Integrate operator counters into query plan to view progress of queries
Date Thu, 06 Aug 2009 18:55:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-713?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12740197#action_12740197

Raghotham Murthy commented on HIVE-713:
---------------------------------------

I am not very familiar with JMX, but it seems useful in cases where command line tools need
to read/modify the internal state of servers. Given that we are only reading stuff from the
operators/tasks, would it be simpler to use a logging based approach like chukwa or scribe?
