Ted Yu commented on HBASE-8626:
-------------------------------
What if another client uses the following code where the value of now is the
same as the value of now obtained above ?
{code}
Delete delete = new Delete(row);
delete.deleteFamily(cf1, now);
Put put2 = new Put(row);
put2.add(cf1, col2, now+1);
{code}
Both put1 and put2 would go through, right ?
> RowMutations fail when Delete and Put on same columnFamily/column/row

> 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: 0.95.1

>
> 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
