Jean-Marc Spaggiari commented on HBASE-8626:
--------------------------------------------
Are we going to be break the compatibility with the previous version?
I mean, if someone is using this today on is code knowing how it's working,
that mean after this patch it will not work anymore, right?
I'm not really convinced this is a bug. Why should we first to the deletes and
not first do the puts...
> RowMutations fail when Delete and Put on same columnFamily/column/row

> 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
