Jean-Marc Spaggiari commented on HBASE-8678:
--------------------------------------------
Ok. I drilled down into the code and found why it's acting that way.
If you want to make you example working fine, just modify it that way:
{code}
Delete delete = new Delete(Bytes.toBytes("row21"));
delete.deleteFamily(Bytes.toBytes("f1"));
delete.setTimestamp(1L);
table.delete(delete);
{code}
Now, what do we want to do.
The REST server is expecting the URL to be key/column/ts/params. Here, we have
not setup any column... So URL was sent as row21/1 when it should have been
row21/f1/1.
We have 2 options.
1) Users will need to add the column in the delete call.
2) From the REST client we send the delete as row21//1 when there is no columns
specified.
I tired 2 and it's working fine, but is it 100 compatible with all existing
usecases? I don't know.
Opinions?

> Components: REST

> Environment: CentOS 5.5/hadoop0.20.2/hbase0.94.5/zookeeper3.4.3
> Reporter: Eric Huang

> 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);
> }
