Subject Re: txntype:unknown reqpath:n/a Error Path:/hbase/unassigned Error:KeeperErrorCode = NodeExists for /hbase/unassigned
Date Thu, 12 May 2011 18:31:08 GMT
These are messages from zookeeper.  On startup, as part of
initialization, all clients of zookeeper will ensure the required
directories are in place in zookeeper.  The below messages are just
saying that someone else beat this client to the creation of /hbase,
/hbase/rs, etc.

We should probably turn down the zk client logging levels but they are
nice to have debugging.  If you don't like them, tinker with your
log4j properties and disable zk client messages.
