Hi , I tried debugging this and got to know that in my master hbase cluster 41181 port is not opened. I tried telnet to this port but connection refused. Following are the steps did :
Start Hadoop Start Hbase Created a table via hbase shell List the contents of table via hbase shell Tried Copytable command. Am I missing something ?

I am then trying to copy m table to other Hadoop-Hbase cluster but facing issues in that . I used following command format : ./hbase org.apache.hadoop.hbase.mapreduce.CopyTable --new.name=<NewTableName> --peer.adr=<different cluster IP>:2181:/hbase <Tablename> But facing issues. Do we also need to do some entry in hdfs-site.xml to do it correctly. Also is there any reqirement of password less ssh in this ?
