Review request for hive, Aihua Xu, Piotr Wikie?, and Thejas Nair.
Bugs: HIVE-15090
https://issues.apache.org/jira/browse/HIVE-15090
Repository: hive-git
Description
-------
Moved the try/catch into the while cycle, so the thread will keep running after
the exception.
Added an extra sleep when there is an exception so we do not end up busy
waiting for the solution of the problem which caused the exception
Diffs

Testing
-------
I have tested with the following configuration:
<property>
<!-- So the tokens are stored in database -->
<name>hive.cluster.delegation.token.store.class</name>
<value>org.apache.hadoop.hive.thrift.DBTokenStore</value>
</property>
<property>
<!-- So the removal happens often -->
<name>hive.cluster.delegation.token.gc-interval</name>
<value>10</value>
</property>
Started the Metastore, and after a while I have stopped the database. When the
database was turned off the metastore logged the ExpiredTokenRemover thread
received unexpected exception message, after the database restarted the
messages are stopped, and everything become normal. In the debugger I have
verified the thread is running.
Thanks,
Peter Vary
