jackonhu commented on HIVE-9893:
--------------------------------
I'm wondering when will hiveserver need so much java heap space ? in error
log,I see there are just some getSchemas method call such as
getSchemas(CLIService.java:277),recv_get_databases(ThriftHiveMetastore.java:600),
how could it take so much space?

> Key: HIVE-9893
> URL: https://issues.apache.org/jira/browse/HIVE-9893
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 0.14.0
> Environment: Vmware Pseudo cluster
> HDP 2.2 Ambari vanilla install
> Centos 6.5
> Reporter: Rupert Bailey
> Labels: Hadoop, Hive, Tez, Thrift
>
> Everything runs but dies after a few days with the Java heap space memory
> error - and with no activity on cluster. It failed most resently after 5 days.
> I tried to fix it after noticing the SLF4J library duplication, wondering if
> conflicting libraries would be causing the error, but still fails.
