Jurriaan Mous updated HBASE-12740:
----------------------------------
Attachment: HBASE-12740-v1.patch
- Added a close to HBaseFsck so it cleans up its internal connection, meta
table and admin. This lowered the open threads in a big way! I also added this
close to more tests which uses HBaseFsck and HBaseFsck created by
HbckTestingUtil now auto closes. (It only closed the resources when run through
exec method and never in tests.)
- Removed more deprecated calls.
Reaction to [~dimaspivak]:
- setupTableWithRegionReplica now returns void
- changed deleteTable to cleanupTable and let it use deleteTable in
HBaseTestingUtility.
- the 7 thread count is now a variable.
> Improve performance of TestHBaseFsck

> TestHBaseFsck performs poor on my machine. It crashes because the threads
> reach the 2000 thread limit on my machine. Looking at the code a lot of
> optimization is possible and some API calls are used wrong. A lot of Admin
> instances are created and never closed, lots of Tables are not closed,
> ThreadPoolExecutors are not shut down and an unlimited thread pool which does
> not recycle threads.
