Jinho Kim commented on TAJO-1197:
---------------------------------
I found some case as following :
* HA unit test does not close the testing cluster
* TajoCli test does not close the jline stream
* Some unit test does not close the TajoClient
* Default RPC threads is too big in unit test
> Unit test failed: unable to create new native thread
