zhangduo updated HBASE-10201:
-----------------------------
    Attachment: HBASE-10201_7.patch

Seems HBASE-12405 must be evaluated by HBASE-10201, so I combined the changes 
together and post it in here. HBASE-12405 can be marked as duplicated with 
HBASE-10201 maybe?

Some comments:
I do not change the way of storeing flushedSequenceIdByRegion in ServerManager. 
We need to change protobuf definition(change CompleteSequenceId in RegionLoad 
from long to a kvlist) if we want to do this, so it may break wire compatible, 
at least a rolling upgrade or downgrade will be difficult.

And also, I do not change the RecoveringRegionLastFlushedSequenceId stored on 
zk when doing distributed log replay. The reason is same.

> 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.
