Andrew Purtell commented on HBASE-10366:
----------------------------------------
Never mind, I see the Phoenix tag. Same difference.
> 0.94 filterRow() may be skipped in 0.96(or onwards) code

> HBASE-6429 combines both filterRow & filterRow(List<KeyValue> kvs) functions
> in Filter.
> While 0.94 code or older, it may not implement hasFilterRow as HBase-6429
> expected because hasFilterRow only returns true when filterRow(List<KeyValue>
> kvs) is overridden not the filterRow(). Therefore, the filterRow() will be
> skipped.
> Since we don't ask 0.94 users to update their existing filter code, the issue
> will cause scan returns unexpected keyvalues and break the backward
> compatibility.
