I think removing the startCacheFlush method may have consequences which are beyond the scope
of this Jira. I'm not sure it removing it would be the right thing, but if you feel strongly
about it then Let's discuss it in a dedicated issue.

Fine. Can do it in another issue.

And for the '<=' to '<' change, I read the code again, it is only a check in abortCacheFlush
so not very critical.

+1 on patch v2. You can try another pre commit run to see if it can pass all the UTs.

Thanks.

> The attribute maxFlushedSeqId in HRegion is used to track the max sequence id in the
store files and is reported to HMaster. When flushing only part of the memstore content this
value might be incorrect and may cause data loss.
