stack commented on HBASE-1620:
------------------------------
Jon explained whats going on here to me in IRC.
Adds constructor that takes the scanners setup doing major compaction rather
than create new ones. The new ones will not have the "do not cache" flag set.
> Need to use special StoreScanner constructor for major compactions (passed
> sf, no caching, etc)
