Subject [jira] [Commented] (HBASE-16504) Replication is not preserving the timestamp of the cell
Date Fri, 26 Aug 2016 06:06:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15438520#comment-15438520

Sai Teja Ranuva commented on HBASE-16504:
-----------------------------------------

Thanks Phil, I think everything makes more sense to me now.
For the case of replication, the cells will already have a timestamp set, so the put timestamp
is of no use.

> The Replication procedure in ReplicationSink.replicateEntries() method is not preserving
the timestamp of the cell. 
> Pointer to the code:
> m = CellUtil.isDelete(cell) ? new Delete(cell.getRowArray(), cell.getRowOffset(),cell.getRowLength())
: new Put(cell.getRowArray(), cell.getRowOffset(),cell.getRowLength());
> The Put and Delete constructors called here assign the timestamp with HConstants.LATEST_TIMESTAMP.
Instead we need to keep the timestamp of the cell here.
> Also there doesn't seem to be a test which checks if replication is preserving the timestamp.
