Subject [jira] [Commented] (HIVE-9100) HiveServer2 fail to connect to MetaStore after MetaStore restarting
Date Mon, 26 Jan 2015 08:56:35 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14291588#comment-14291588

Mariusz Strzelecki commented on HIVE-9100:
------------------------------------------

Hi,
have you tried setting {{hive.cluster.delegation.token.store.class}} in metastore? By default
all delegation tokens are stored in metastore's memory and service restart removes all of
them. Metastore supports storing them in database or ZooKeeper (https://github.com/apache/hive/search?utf8=%E2%9C%93&q=%22implements+DelegationTokenStore%22&type=Code)

For me, setting:
{noformat}
<property>
  <name>hive.cluster.delegation.token.store.class</name>
  <value>org.apache.hadoop.hive.thrift.DBTokenStore</value>
</property>
{noformat}
helped with this issue.
