Jonathan Gray commented on HBASE-1620:
--------------------------------------
Definitely possible, though it's really from HBASE-1597 and then the
reimplementation in HBASE-1615 not this issue (which is for major).
I'm unsure why this would not have impacted the old LRU... I would expect the
new one to be faster not slower.
> Need to use special StoreScanner constructor for major compactions (passed
> sf, no caching, etc)
