Symptoms

In an environment supporting Sentry, monitoring "Host CPU Usage" in CM Chart Builder shows HiveServer2 (HS2) steadily increasing its memory usage eventually crashing on Node 4 (the default HS2 server) with Out of Memory(OOM) errors. Following "On Oracle Big Data Appliance Hive Server2 Goes Down when there is Heavy Load" (Doc ID 1913226.1) delays but does not prevent the eventually OOM and HS2 crash.

Following the suggestions on  closing all the queries in the Cloudera blog on:  Hive and Impala queries life cycle  does not help resolve the memory increase either.
