[jira] [Updated] (HIVE-16323) HS2 JDOPersistenceManagerFactory.pmCache leaks after HIVE-14204

     [ https://issues.apache.org/jira/browse/HIVE-16323?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Dai updated HIVE-16323:
------------------------------
    Attachment: HIVE-16323.3.patch

Switch metaStoreClient to getMSC, also close syncMetaStoreClient as Thejas commented.

I think this Hive client is only shared with load-dynamic-partitions threads, and within the threads, write operations are synchronized via SynchronizedMetaStoreClient. cc [~rajesh.balamohan].

> Hive.loadDynamicPartitions creates threads with new embedded rawstore, but never close them, thus we leak PersistenceManager one per such thread.
