Review request for hive and Ashutosh Chauhan.


1. HCatalog tests were failing as they ended up creating client/HMS too many times and threadPool
was getting created every time. This caused rejection exceptions. FS threadpool created here
can be static and be shared across. Made it static.

2. Renamed variable to "hive.metastore.fshandler.threads" as Ashutosh suggested.

3. Ran HCatalog tests locally to ensure it passes.

Bugs: HIVE-13901

Repository: hive-git


Depending on FS, creating external tables & adding partitions can be expensive (e.g msck
which adds all partitions).

Diffs (updated)
