Sergey Shelukhin commented on HBASE-9155:
-----------------------------------------

Hmm... then this is not a realistic scenario for updates/deletes, right? So it 
can hardly verify scanning from multiple files, compaction effect, reading old 
data etc.
It will always update data that was just written, before it's ever read.
I wonder what is the use case.

> We can enhance LoadTestTool to support updates like 
> increment/append/checkAndPut/checkAndDelete to make sure these operations 
> work as expected during integration testing.
> If chaosmonkey is enabled, increment/append could be invoked multiple times. 
> During verification, we need to keep this in mind before they are guaranteed 
> to be called only once in the sever side.
