Sergey Shelukhin updated HIVE-12161:
------------------------------------
    Description: 
Before merge, the test took 4~hrs (total time parallelized, not wall clock 
time), after the merge it's taking 12-15hrs. First such build:
http://ec2-174-129-184-35.compute-1.amazonaws.com/jenkins/job/PreCommit-HIVE-TRUNK-Build/5622/testReport/org.apache.hadoop.hive.cli/TestMiniTezCliDriver/

-Session reuse patch which used to make them super fast now makes them run in 
2hrs 
http://ec2-174-129-184-35.compute-1.amazonaws.com/jenkins/job/PreCommit-HIVE-TRUNK-Build/5628/testReport/org.apache.hadoop.hive.cli/TestMiniTezCliDriver/
 which is still a lot.- This is invalid

Need to investigate why tests are slow regardless of AM reuse.
