I am trying to copy a table created on mapr m3/m5 cluster say 'table01' to m7 cluster, I use following command on m7 cluster edge node (source.zk1,source.zk2,source.zk3 are zookeeper nodes on my source m3 cluster with port 5181, and i have already created a table /mapr/m7cluster/tables/table01 on m7)-

<code>
/opt/mapr/hbase/hbase-0.94.9/bin/hbase org.apache.hadoop.hbase.mapreduce.CopyTable -Dhbase.zookeeper.quorum=source.zk1,source.zk2,source.zk3 -Dhbase.zookeeper.property.clientPort=5181 --new.name=\/mapr\/m7cluster\/tables\/table01 table01.
</code>

it throws following exception -
<pre>
14/02/19 08:52:58 ERROR mapreduce.TableInputFormat: org.apache.hadoop.hbase.client.NoServerForRegionException: Unable to find region for table01,,99999999999999 after 10 tries.
