Subject [jira] [Commented] (HIVE-12526) PerfLogger for hive compiler and optimizer
Date Tue, 01 Dec 2015 21:22:10 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12526?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15034600#comment-15034600

Ashutosh Chauhan commented on HIVE-12526:
-----------------------------------------

Patch LGTM +1 For performance, its not inside any loop and is called for each optimization
phase, so should not be a drain. 
[~hsubramaniyan] Can you post output of new log lines generated on a non-trivial query so
that we have an idea of how it will look like.
