From time to time we see messages as jvm pause defected from HiveMetastore & Hiveserver2 logs in spite we increased the heap size to the right size ( according to number of connection to HIVE reference - https://www.linkedin.com/pulse/tuning-apache-hive-cdh-sadique-arrvi/)
we don't sure if the default Garbage Collectors - Parallel , is good enough , and since our HIVE service is under huge load
so this make me to think about other Garbage Collectors as CMS or G1 ?
