----------------------------------------

             Summary: JDBC : ResultSetMetaData.isNullable returns true even when the column
is a required one
                 Key: DRILL-2462
                 URL: https://issues.apache.org/jira/browse/DRILL-2462

            Priority: Critical
         Attachments: fewtypes.parquet

git.commit.id.abbrev=7b4c887

I attached a parquet file in which all the columns are required
{code}
/root/parquet-tools-1.5.1-SNAPSHOT/parquet-tools schema fewtypes.parquet
message root {
  required int32 int_col;
  required int64 bigint_col;
  required int32 date_col (DATE);
  required int32 time_col (TIME);
  required int64 timestamp_col (TIMESTAMP);
  required binary interval_col (UTF8);
  required binary varchar_col (UTF8);
  required float float_col;
  required double double_col;
  required boolean bool_col;
}
{code}

However ResultSetMetaData.isNullable returns true for these columns.

Let me know if you need anythig
