Subject: Issues in CopyTable to different cluster

Hi,

I was trying copytable utility and it worked fine in same cluster but not working properly
with different cluster when I try to copy my table from 1 cluster to other .

Command I used :

"Hbase/hbase-0.90.3/bin/hbase org.apache.hadoop.hbase.mapreduce.CopyTable --starttime=1315916685308
--endtime=1315997062277 --new.name=backup --peer.adr=slave1:2181:/hbase testArchive"

IP and hostname of each cluster machines are present in each other hostfile.

Error :
11/09/15 13:13:08 INFO zookeeper.ClientCnxn: Session establishment complete on server slave1/172.28.96.239:2181,

Am I missing something ?
