zhangduo updated HBASE-10201:
-----------------------------

According to Ted Yu's suggestion, add a testcase called testCompareStoreFileCount in TestPerColumnFamilyFlush
to confirm we really reduce the number of store files with this patch.

> Currently the flush decision is made using the aggregate size of all column families.
When large and small column families co-exist, this causes many small flushes of the smaller
CF. We need to make per-CF flush decisions.
