Description

From the user point of view, If I want to invoke a major compact manually, What I want is that all separate file and the memstore is combined into one file. If I don't write anything new there, from the user point of view, I will assume that it will end up in a single store file per region. And all the VERSIONS limit etc staffs will be respected. I don't wish it flush memstore later and create another small store file. At present,it seems to me both major_compact and compact API and hbase shell cmd don't do memstore flush.
