Subject [jira] [Commented] (HIVE-12281) Vectorized MapJoin - use Operator::isLogDebugEnabled
Date Wed, 28 Oct 2015 18:00:31 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12281?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14978907#comment-14978907

Gopal V commented on HIVE-12281:
--------------------------------

There's an HTTP UI interface in LLAP which lets you turn on logging for a specific Operator
class in LLAP.

It's exactly as fast now, so leave that in place just in case we ever have to debug it without
restarting?
