-------------------------------------------------------

Is is possible that we have a case where forcing flush after the checks is more appropriate
than forcing before? When it should be done?

Let's say we have a region1 having faulty data. We have run hbasck. It forced flush and we
now have region11 and region12. If region1 did not have faulty data, we would have only region1.
Later the compaction resolved this, but split and compaction ran for nothing in this region
server.

If i am wrong, please point me what to look for.
