Ted Yu commented on HBASE-11093:
--------------------------------
User filter should follow Filter javadoc, which is clear since 0.96+, and
implement hasFilterRow() accordingly.
The snippet cited above makes filtering inefficient and somewhat hard to
predict.
We should make a decision as to which release drops this snippet.
> FilterList#filterRow() iterates through its filters even though
> FilterList#hasFilterRow() returns false

> FilterList#hasFilterRow() returns false when hasFilterRow() of all of
> constituent filters return false.
> However, FilterList#filterRow() still iterates through its filters in this
> scenario.
> The iteration should be skipped when FilterList#hasFilterRow() returns false.
