> The current easy solution without adding extra code in 94/95 is to use snapshots
> {code}
> hbase shell> disable 'tableName'
> hbase shell> snapshot 'tableName', 'tableSnapshot'
> hbase shell> clone 'tableSnapshot', 'newTableName'
> hbase shell> delete_snapshot 'tableSnapshot'
> {code}
> {code}

>     String snapshotName = randomName();
>     admin.snapshot(snapshotName, oldTableName);
>     admin.cloneSnapshot(snapshotName, newTableName);
>     admin.deleteSnapshot(snapshotName);
