Subject [jira] [Updated] (HIVE-7353) HiveServer2 using embedded MetaStore leaks JDOPersistanceManager
Date Tue, 11 Nov 2014 22:30:35 GMT

     [ https://issues.apache.org/jira/browse/HIVE-7353?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Szehon Ho updated HIVE-7353:
----------------------------
    Labels:   (was: TODOC14)

Added description (verbatim) for : 
hive.server2.thrift.http.worker.keepalive.time, hive.server2.thrift.worker.keepalive.time


at specified location at [https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties|https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties]

FYI [~leftylev].  Also I assume we are removing TODOC label after doc but before you review,
hope thats right.

> While using embedded metastore, while creating background threads to run async operations,
HiveServer2 ends up creating new instances of JDOPersistanceManager which are cached in JDOPersistanceManagerFactory.
Even when the background thread is killed by the thread pool manager, the JDOPersistanceManager
are never GCed because they are cached by JDOPersistanceManagerFactory.
