[jira] [Updated] (HBASE-4947) CopyTable warns about being unable to
find table from wrong instance of HBase
Posted by "Jonathan Hsieh (Updated) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-4947?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Hsieh updated HBASE-4947:
----------------------------------
Description:
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}
