Subject [jira] Created: (HBASE-1842) HTablePool -- Ride Over Restart
Date Wed, 16 Sep 2009 00:04:57 GMT
HTablePool -- Ride Over Restart

                 Key: HBASE-1842
                 URL: https://issues.apache.org/jira/browse/HBASE-1842
             Project: Hadoop HBase
          Issue Type: Bug
          Components: client
    Affects Versions: 0.20.0
         Environment: Configuration:
Hbase 0.20.0 & Hadoop 0.20.1
Pseudo distributed mode
Java client using HTablePool
            Reporter: Barney Frank

When ZK, Master, Regionserver and my app are running, I stop the Hbase master/regionserver.
 The HBaseClient then begins to complain:
16:26:51,273 INFO [HBaseClient] Retrying connect to server: / Already tried
0 time(s).
16:26:53,274 INFO [HBaseClient] Retrying connect to server: / Already tried
1 time(s).
...already tried 9 time(s)....
16:27:10,294 INFO [HbaseRPC] Server at / not available yet, Zzzzz...

I restart the Master and RegionServer and then send more client requests through HTablePool.
 It has the same "Retrying to connect to server:" messages.  I noticed that the port number
it is using is the old port for the region server and not the new one assigned after the restart.
 The HbaseClient does not seem to recover unless I restart the client app.  When I do not
use HTablePool and only Htable it works fine.

When using HTablePool, the client doesn't seem to refresh with the new regionserver port after
the master/regions are back up.  It gets "stuck" with the info from the settings prior to
the master going down.  The ability to ride over a restart.

I would appreciate any thoughts or help.
