Subject HBASE-5780
Date Tue, 17 Jul 2012 20:54:08 GMT

I upgraded to hbase 0.94.0 which was supposed to fix HBASE-5780 issue.  It initially worked
but I am still getting intermittent failures when region servers communicate with zookeeper.
 It appears that the authentication is successful, but 

On the zookeeper server:
12/07/17 16:47:16 INFO auth.SaslServerCallbackHandler: Successfully authenticated client:
authenticationID=hbase/rdcesx12082.race.sas.com@OBSIDIAN.SAS.COM;  authorizationID=hbase/rdcesx12082.race.sas.com@OBSIDIAN.SAS.COM.
12/07/17 16:47:16 INFO auth.SaslServerCallbackHandler: Setting authorizedID: hbase
12/07/17 16:47:16 INFO server.ZooKeeperServer: adding SASL authorization for authorizationID:
12/07/17 16:47:21 WARN server.NIOServerCnxn: caught end of stream exception
EndOfStreamException: Unable to read additional data from client sessionid 0x1389637a5f10003,
likely client has closed socket

Looks like the client hbase/rdcesx12082.race.sas.com@OBSIDIAN.SAS.COM authenticated successfully.
 Then it received an unexpected end of stream.

On the server rdcesx11017.race.sas.com, I see the following:
12/07/17 16:47:16 INFO zookeeper.ClientCnxn: Session establishment complete on server rdcesx11017.race.sas.com/,

org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /hbase/shutdown

It appears that the session was established, then "Unable to get data of znode /hbase/shutdown".

Previously, I killed the process so maybe the znode data was not saved appropriately.  Is
there a way to make sure zookeeper data is clean?
