[jira] [Updated] (HIVE-6427) Hive Server2 should reopen Metastore
client in case of any Thrift exceptions
[ https://issues.apache.org/jira/browse/HIVE-6427?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrey Stepachev updated HIVE-6427:
-----------------------------------
Description:
In case of metastore restart hive server doesn't reopen connection to metastore. Any command gives broken pipe or similar exceptions.
http://paste.ubuntu.com/6926215/
Any other subsequent request doesn't reestablish connection and tries to use stale (closed) connection.
Looks like we shouldn't blindly convert any MetaException to HiveSQLException, but should distinguish fatal exceptoins and logical exceptions.
