Hi Butlerh ,
I have modified my cluster settings. Now I specified each machines IP and
hostname in etc/hosts file.
Hbase-conf-site.xml
<name>hbase.rootdir</name>
<value>hdfs://master2:54310/hbase</value>
</property>
Here master2 is hostname given for backup cluster IP but still facing same
issue.
Please suggest
Thanks

If you are doing distributed clusters (even pseudo-distributed), I don't think
you should be using localhost as the address. Especially if you want to
communicate between two different clusters

Subject: RE: Hbase copytable and export/import
Hi Jean,
I will try to explain more clearly. I have 2 cluster each single node Hadoop
and Hbase cluster. I can create tables and perform other operation of Hbase in
both the cluster individually. Now I wanted to copy a table from 1 cluster (say
A) to other cluster (say B).
In both the cluster, hbase-site.xml looks like this :
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:54310/hbase</value>
</property>
<property>
<name>dfs.replication</name>
<value>1</value>
<description>The replication count for HLog and HFile storage. Should not
be greater than HDFS datanode count.
</description>
</property>
</configuration>
Thanks

Your remote cluster reports the location of -ROOT- as on localhost on port
41181:
11/08/30 19:27:47 DEBUG
client.HConnectionManager$HConnectionImplementation: Lookedup root region
location,
connection=org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@10d593e<connection=org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@10d593e<mailto:connection=org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@10d593e%3cconnection=org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@10d593e>>;
hsa=localhost:41181
(hsa is the name of the class in HBase, HServerAddress)
Is that "cluster" really just a standalone instance or something like that?
That's usually what happens.
