Lars Hofhansl commented on HBASE-753:
-------------------------------------
Something like this might still be useful, this would be far more efficient
than a copy based on cells.
> Safe copy of tables using hdfs copy (WAS -> Can't replace the data of a
> particular table by copying its files on HDFS)

> Key: HBASE-753
> URL: https://issues.apache.org/jira/browse/HBASE-753
> Project: HBase
> Issue Type: New Feature
> Affects Versions: 0.2.0
> Reporter: Sebastien Rainville
> Priority: Minor
>
> I have 2 instances of hbase running. One is *production* and the other one is
> *development*. I want to be able to replace the content of a table (not all
> of them) in development by the content in production. Both of my environments
> are running hbase-trunk (a snapshot of july 9th). In hbase-0.1.x we used to
> be able to do that by simply stopping both hbases, copying the files of the
> required table directly from one HDFS to the other and then restart hbase.
> It doesn't work anymore. In hbase shell I do see the table but it's empty.
> There are no errors. I looked at the master's log and the regionservers logs
> as well, all in DEBUG mode... but I saw nothing interesting. I do see that
> the regions for that table are being assigned. So, if there's more than 1
> region it means that it knows that the table isn't empty.
> So, I have to copy all the tables and then it's fine. It's not practical
> though.
> My guess is that .META. is holding old information about that table that
> doesn't get updated when I replace the table's data.
