Description

git.commit.id.abbrev=7b4c887

I attached a parquet file which has nulls in it.

while (rs.next()) {
    rs.getLong(1);
    if (rs.wasNull()) {
       // DRILL does not come here even when the column value is null
    }
}

I am not entirely sure if this is a duplicate to DRILL-2136. But here I have seen this happen for all data types.
