Anoop Sam John commented on HBASE-11093:
----------------------------------------
In HRegion#RegionScannerImpl
Wherever we call filterRowCells() or filterRow() we have hasFilterRow() checks
prior to those..
{code}
private boolean filterRow() throws IOException {
// when hasFilterRow returns true, filter.filterRow() will be called
automatically inside
// filterRowCells(List<Cell> kvs) so we skip that scenario here.
return filter != null && (!filter.hasFilterRow())
&& filter.filterRow();
}
{code}
For BC we make above code. Here even if hasFilterRow is false we have to call
filterRow(). With this patch, we will fail to call filterRow() right?
> 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.
