Lars Hofhansl commented on HBASE-8626:
--------------------------------------
The semantics of RowMutation are that all edits are applied in one MVCC
snapshot and written to a single WALEdit. There are no assumptions about
Put/Delete timestamps whatsoever.
The client is free to set timestamps as desired. The Vinod's example above the
Puts just need to have a timestamp higher than the Delete. The client can make
that so.
{code}
long now = System.currentTimeMillis();
Delete delete = new Delete(row);
delete.deleteFamily(cf1, now);
Put put1 = new Put(row);
put1.add(cf1,col1,now+1);
{code}
Let's not make this more complicated that it has to be. I maintain my -1 on
changing this.

> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.94.7, 0.95.0
> Environment: Ubuntu 12.04, HBase 0.94.7
> Reporter: Vinod
> Assignee: Ted Yu
> Fix For: 0.94.7, 0.95.1
>
> Attachments: 8626-v1.txt, TestRowMutations.java,
> tests_for_row_mutations1.patch
>
>
> When RowMutations have a Delete followed by Put to same column family or
> columns or rows, only the Delete is happening while the Put is ignored so
> atomicity of RowMutations is broken for such cases.
> Attached is a unit test where the following tests are failing:
> - testDeleteCFThenPutInSameCF: Delete a column family and then Put to same
> column family.
> - testDeleteColumnThenPutSameColumn: Delete a column and then Put to same
> column.
> - testDeleteRowThenPutSameRow: Delete a row and then Put to same row
