Hey, [~ram_krish] !!

Thank you for taking the look and making the run.
In the given patch, we are always merging the newly-pushed segment with the old 
one. Therefore, policy never returns FLATTEN, because 
So I wonder why do you say: "the flush is not flushing all the segments". It 
actually should...

Maybe what you experience is the effect of the flush waiting for the merging to 
be done. 
We also agree that we should better avoid this waiting and it will be 
eliminated in the next patch.
Currently, (after HBASE-16229 is in)  the re-base takes me some long time. 
Mostly the testing part. A lot of tests need to be fixed.
I hope to resolve all the issues in the coming days and to provide a new patch, 
which is including the fixes for your code review.
