Review request for hive, Zoltan Haindrich, Zoltan Haindrich, Naveen Gangam, and 
Peter Vary.


Bugs: HIVE-20535
    https://issues.apache.org/jira/browse/HIVE-20535


Repository: hive-git


Description
-------

When removing the compile lock, it is quite risky to remove it entirely.

It would be good to provide a pool size for the concurrent compilation, so the 
administrator can limit the load
