Subject Problem with port 2181
Date Thu, 26 Jan 2012 04:52:33 GMT
Hi,  I have a pseudo distributed cluster of CDH3 U1.  I am running Hadoop and
HBase.   I have not installed zookeeper separately in it's own directory so
when I startup HBase, I guess the default embedded zookeeper process
(HQuorumPeer) process starts up.

The problem is,  I am trying to connect to HBase from an external client, 
with localhost and port 2181.   In the zookeeper logs, I do see that it
receives the request but the client is not able to get the required info
which is the list of HBase tables,  I see the following messages in the log
file,
