hyoungjunkim commented on TAJO-646:
-----------------------------------
TajoClient has its own a ConnectionPool for thread safety. But in the previous
implementation ServerCallable class calls RpcConnectionPool.getPool() which is
shared. In this patch I changed that ServerCallable's constructor has
ConnectionPool parameter.
Please review this patch. Thanks
