Lars Hofhansl commented on PHOENIX-5291:
----------------------------------------

[~rushabh.shah], [~ram_krish]

Can we undo the reference counting please! I know this was a big change, but 
we've had continuing outages over that. Reference counting by it's nature is 
fickle in a big system like HBase.
In any case, I'll post a patch here to close the scanners correctly.

> With HBase 1.5 and later this is a disaster, as it causes the wrong reference 
> counting of HFiles in HBase, and those subsequently will *never* be removed 
> until the region closes and reopens for any reason.
> We found at least two cases... See comments below.
