Subject [jira] Updated: (HBASE-3095) Client needs to reconnect if it expires its zk session
Date Fri, 08 Oct 2010 20:04:34 GMT

     [ https://issues.apache.org/jira/browse/HBASE-3095?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

stack updated HBASE-3095:
-------------------------

    Fix Version/s: 0.90.0

I'm putting this in 0.90 for now.  Its marked a major bug rather than critical or blocker
so could get punted.  My sense though is that this is something that could become an irritant.
 Lets see.  I'll let the issue stew some before going about fixing.

> Clients use an HConnection down in their guts to connect to the hbase cluster.  Master-is-running
and root-region-location are up in zk.   Setup of a new HConnection sets up a connection to
ZooKeeper.  If the session with ZK expires for whatever reason -- in tests they would expire
because zk ensemble was restarted across tests or we might expire because of a long GC, well,
it'll be frustrating to users if we do not just try and resetup the zk connection.
