Jonathan Gray updated HBASE-1620:
---------------------------------

    Status: Patch Available  (was: Open)

Also does not add to changed readers observer list.  We don't want to add newly 
flushed storefiles midway through compaction.  In the future, we could snapshot 
 the memcache and include it in the major compaction.  Would be a good way to 
help keep storefiles low.

Ready for commit.

> Need to use special StoreScanner constructor for major compactions (passed 
> sf, no caching, etc)
