Aditya Kishore commented on DRILL-1403:
---------------------------------------
I tried the following query and it seems to be pushing the filter correctly
(with the patch of course).
{code}
select cast(t.f.c as varchar(20)) from t where row_key > 'row1' and row_key <
'row5';
select cast(f['c'] as varchar(20)) from t where row_key > 'row1' and row_key <
'row5';
{code}
> HBase predicate pushdown filters are not getting applied
