[jira] Updated: (HBASE-2849) Clients stuck in loop doing
"NIOServerCnxn: Closed socket connection"
[ https://issues.apache.org/jira/browse/HBASE-2849?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Benoit Sigoure updated HBASE-2849:
----------------------------------
Description:
Someone made mention of this loop last week but I don't think I filed an issue. Here is another instance, again from a secret hbase admirer:
"It seems that when Zookeeper dies and restarts, all client applications need to be restarted too. I just restarted HBase in non-distributed mode (which includes a ZK) and now my application can't reconnect to ZK unless I restart it too. I'm stuck in this loop:
{code}
2010-07-19 00:13:05,725 INFO org.apache.zookeeper.server.NIOServerCnxn:
Closed socket connection for client /127.0.0.1:55153 (no session established for client)
2010-07-19 00:13:07,052 INFO org.apache.zookeeper.server.NIOServerCnxn:
Accepted socket connection from /127.0.0.1:55154
2010-07-19 00:13:07,053 INFO org.apache.zookeeper.server.NIOServerCnxn:
Refusing session request for client /127.0.0.1:55154 as it has seen zxid 0xf5 our last zxid is 0xd7
client must try another server
{code}

Reformatting a little bit.
