Date Tue, 12 Mar 2019 11:50:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16790464#comment-16790464

chenjianxun commented on HIVE-14430:
------------------------------------

is there any progess for this issue?

i have got the same problem, the instances of "org.apache.hadoop.hive.conf.HiveConf" keep
growing.

and the dump file of hiveserver2 shows that there is a memory leak problem

i am using hive 2.3.4 and hadoop-2.6.0-cdh5.16.1

 

Leak Suspects
1,041 instances of *"org.apache.hadoop.hive.conf.HiveConf"*, loaded by *"sun.misc.Launcher$AppClassLoader
@ 0xeaaa0058"* occupy *270,268,056 (52.70%)* bytes. These instances are referenced from
one instance of *"java.util.HashMap$Node[]"*, loaded by *"<system class loader>"*

> 841 instances of HiveConf.
> 831 instances of UDFClassLoader
> This is on a HS2 instance configured to run 10 concurrent queries with LLAP.
> 10 SessionState instances. Something is holding on to the additional HiveConf, UDFClassLoaders
- potentially HMSHandler.
> This is with an embedded metastore.
