--------------------------------
Component/s: mapreduce
> CopyTable warns about being unable to find table from wrong instance of HBase
> -----------------------------------------------------------------------------
>
> Key: HBASE-4947
> URL: https://issues.apache.org/jira/browse/HBASE-4947
> Project: HBase
> Issue Type: Bug
> Components: mapreduce
> Affects Versions: 0.90.4, 0.92.0
> Reporter: Jonathan Hsieh
> Priority: Minor
>
> Using CopyTable with two clusters, test01 and test02.
> cluster cluster01 has a table called 'table' which has a little bit of data
> in it.
> cluster cluster02 has a table called 'table2' which have the same schema as
> cluster01's 'table'
> Here's the command line used from a machine in cluster01
> {code}
> $ hbase org.apache.hadoop.hbase.mapreduce.CopyTable
> --peer.adr=cluster02:2181:/hbase --new.name=table2 table
> {code}
> Job succeeds, but gives a scary extraneous warning:
> {code}
