> PhoenixRelation does not implement unhandledFilters so the data returned from a scan
is run through filters twice.

> Project [ID#7L]
> +- Filter (((isnotnull(COL1#8) && isnotnull(ID#7L)) && (COL1#8 = test_row_1))
&& (ID#7L = 1))
>    +- Scan PhoenixRelation(TABLE1,localhost:50068:/hbase,false) [ID#7L,COL1#8] PushedFilters:
[IsNotNull(COL1), IsNotNull(ID), EqualTo(COL1,test_row_1), EqualTo(ID,1)], ReadSchema: struct<ID:bigint>
> {code}
