Subject [jira] [Commented] (HBASE-8678) Wrongly delete cells in some case which can not be deleted
Date Tue, 09 Jul 2013 13:43:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8678?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13703269#comment-13703269
] 

Lars George commented on HBASE-8678:
------------------------------------

Yes, please check the patch against trunk if you can (though I would not assume for it to
fail). I would also assume it applies to 0.94 with just removing the maven module path (i.e.
drop "hbase-server/"). But try both once more if you can please. Thanks JM!

> First, I put a cell using put interface, but I don't specify timestamp. Then I delete
the the same row, specify a timestamp of 1L. Unfortunately, the former cell is 
> deleted. We should know this cell can not be deleted in this case. (Using original Client
API)
> Code like this;
> public static void main(String[] args) throws Exception {
>         Cluster cluster = new Cluster();
>         cluster.add("10.28.171.38", 8080);
>         Client client = new Client(cluster);
>         RemoteHTable table = new RemoteHTable(client, "demotime");
>                 
>         Put put = new Put(Bytes.toBytes("row21"));
>         put.add("info".getBytes(), "name".getBytes(), "huanggang".getBytes());
>         table.put(put);
>         
>         Delete delete = new Delete(Bytes.toBytes("row21"));
>         delete.setTimestamp(1L);
>         table.delete(delete);
>     }
