Thanks Ted for comments!

Why was COMPACT_REGION added to the above check ?

In tests, I found major compaction requests drag recovery process. Current recovered edits recovery doesn't allow compaction. So I disable compaction request for log replay recovery as well.

I incorporated the rest comments into v4 patch. Thanks.

> In HLogSplitter:locateRegionAndRefreshLastFlushedSequenceId(HConnection, byte[], byte[], String), we talk to the replayee regionserver to figure out whether a region is in recovery or not. We should look at ZK only for this piece of information (since that is the source of truth for recovery otherwise).
