Jeongmin Kim commented on HBASE-22835:
--------------------------------------
I think, unless 1.3 is EOM yet, there can be users who struggle with the same
problem. Whether next release is comming or not, Reviewing and confirming that
this is right solution still worth for them. (maybe they can build theirselves)
> Scan/Get with setColumn and the store with ROWCOL bloom filter could throw
> AssertionError (backport of HBASE-19863)

> Scan/Get with setColumn and the store with ROWCOL bloom filter could throw
> AssertionError of scan order check.
> which is resolved by HBASE-19863 for 1.4, 2.x, or later version.
> A same bug exists in branch 1.3 and older, and also my cluster suffered from
> the same problem.
>
> When ROWCOL bloomFilter is enabled and fake cell is the prevCell,
> actual hfs offset can be behind, in this case heap.next() is not enough. it
> requires reseek to find right next cell.

> I created a backport patch of -HBASE-19863 and *HBASE-17958*-.
> Exact same testcase included. And changed StoreScanner due to the difference
> of codes.
