1- What HBase version are you use?
2- Which O.S are you using?
3- Which are the permitions on those directories:
      /hbase/unassigned
      /hbase/rs
      /hbase/table

1- What HBase version are you use?
hbase-0.90.1
2- Which O.S are you using?
CentOS 5.5 x8_64
3- Which are the permitions on those directories:
    /hbase/unassigned
    /hbase/rs
    /hbase/table
These tables/dir doesn't exist.

As I understood these are the INFO level logs. But curious to know the
reason of this.

Thanks,
Shah

Well, searching more deep on the KeeperException.java file (inside of
the package org.apache.zookeeper), this exception is because a node that
you trying to set up, is already on the Zookeeper configuration.
Which nodes are you have in the zoo.cfg?

I installed hbase on my Mac Os 10.6 machine and when i try to run hbase master start I get the following error:

my error is similar if not the same with the following thread
http://article.gmane.org/gmane.comp.java.hadoop.hbase.user/17432/match=got+user+level+keeperexception+processing+sessionid
but it did not give any solution

Thank your for your time and help
