Varun Sharma commented on HBASE-4583:
-------------------------------------
In the spirit of HBASE-7051 which fixes the race condition between put and
checkAndPut for both 0.94 and 0.96 - I think we should at least fix the race
condition for 0.94 for Append and Increment operations, like we did for
checkAndPut. I would also be in favour of fixing the entire issue for 0.94, now
that we have a very elegant and clear patch for 0.96. Unless, there are strong
objections, I can help replicate this patch for 0.94 ?
> Integrate RWCC with Append and Increment operations

> Currently Increment and Append operations do not work with RWCC and hence a
> client could see the results of multiple such operation mixed in the same
> Get/Scan.
> The semantics might be a bit more interesting here as upsert adds and removes
> to and from the memstore.
