retries

Hi JM,

Thanks for your reply .
The problem is with the /etc/hosts file .After changing the entry
127.0.1.1  <computer name> to
local lan ip <computer name> (eg : 192.168.2.40 <computer name>

its working for me.

Thanks,
Bharadwaj

Hi Bharadwaj,

Have you tried to connect to you ZooKeeper shell to see if you have
access to the node /hbase/master?

You can take a look there:
http://zookeeper.apache.org/doc/r3.2.2/zookeeperStarted.html to access
the shell.
