CopyTable from Hbase 0.90.4 to Hbase 0.94.6 not working

I'm trying to copy table from Hbase 0.90 to Hbase 0.04 with this command:

$ hbase org.apache.hadoop.hbase.mapreduce.CopyTable --peer.adr=ZKHOST:2181:/hbase --starttime=1378252486000 --endtime=1378338886000 --new.name=my_table my_table

But I'm getting this error:

13/09/04 21:52:12 INFO mapred.JobClient: Running job: job_201305141438_0003
13/09/04 21:52:13 INFO mapred.JobClient:  map 0% reduce 0%

I have 10 hosts in new the destination system hbase01 to hbase10. The script automatically picks 1 host, but I'm not sure why it is trying to use something like 'hbase10.dc.yyy.nethbase10.dc.yyy.net', that looks wrong to me.

Yes copy table needs to be able to connect to both clusters. They will need to be RPC compatible.

  • 0.90 -> 0.90
  • 0.92 -> 0.92, 0.94
  • 0.94 -> 0.92, 0.94
  • 0.96 -> 0.96

Perhaps export/import can be used to do what you are looking for ?
