zhangduo updated HBASE-10201:
-----------------------------
Attachment: HBASE-10201_18.patch
Rename lastFlushSeqId to maxFlushedSeqId in HRegion. Always generate a
flushSeqId with incrementing of sequenceId and now maxFlushedSeqId is not equal
to flushSeqId.
Rename FlushLargeStorePolicy to FlushLargeAndOldStorePolicy that also flush
store which make HRegion.shouldFlush, and change forceFlushAllStores flag to
false in PeriodicMemstoreFlusher.
> Port 'Make flush decisions per column family' to trunk

> 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.
