Phabricator updated HIVE-2969:
------------------------------

    Attachment: HIVE-2969.D2919.1.patch

kevinwilfong requested code review of "HIVE-2969 [jira] Log Time To Submit metric with PerfLogger".
Reviewers: JIRA

  https://issues.apache.org/jira/browse/HIVE-2969

  Added Time To Submit to the PerfLogger, beginning just after the PerfLogger is first initialized,
and ending just before the loop which starts submitting jobs to map reduce.

  Logging the time from when Driver.run starts to when we begin submitting jobs to map reduce
would be helpful in determining how much of the lag in starting a query is due to Hive vs.
Hadoop.
