> Reporter: Jeongmin Kim
> Priority: Major
> Fix For: 1.3.6
>
> Attachments: HBASE-22835.patch
>
>
> 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.
> Exact same testcase included. And changed StoreScanner due to the difference
> of codes.
