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

[~tdsilva], I suppose we could have this in 4.14 and perhaps even delay the RC, since this is potentially pretty bad.

> 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.
