Ted Yu commented on HBASE-11093:
--------------------------------
w.r.t. Anoop's suggestion, in HRegion, filterRowCells() call is guarded by
hasFilterRow() :
{code}
if (filter != null && filter.hasFilterRow()) {
filter.filterRowCells(results);
}
{code}
{code}
if (filter != null && filter.hasFilterRow()) {
ret = filter.filterRowCellsWithRet(results);
}
{code}
HRegion doesn't call filterRow(List). In fact, see the following in
FilterWrapper:
{code}
public void filterRow(List<KeyValue> kvs) throws IOException {
// This is only used internally, marked InterfaceAudience.private, and not
used anywhere.
// We can get away with not implementing this.
throw new UnsupportedOperationException("filterRow(List<KeyValue>) should
never be called");
}
{code}
> 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.
