Do not pull counters of non initialized jobs
--------------------------------------------
Key: HIVE-1349
URL: https://issues.apache.org/jira/browse/HIVE-1349
Project: Hadoop Hive
Issue Type: Improvement
Reporter: Dmytro Molkov
Right now hive client puts a lot of pressure on the jobtracker by pulling the
counters of the job that has just been submitted and is in the process of
initializing tasks.
While the job initialized tasks and reads the splits file it is holding the
JobInProgress lock. The getCounters method acquires a JobTracker lock and waits
for the JobInProgress lock. Since the read of the file can take a couple (a
couple of tens of seconds) the job tracker is effectively blocked for that
period of time.
