Krystal created DRILL-4062:
------------------------------

             Summary: SUM function does not work against interval data type 
from csv or json files
                 Key: DRILL-4062
                 URL: https://issues.apache.org/jira/browse/DRILL-4062
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill
            Reporter: Krystal


I have a csv table with the following interval year data:
select columns[1] from `interval_data.csv`;
+---------+
| EXPR$0  |
+---------+
| P12Y    |
| P152Y   |
| P-152Y  |
| P5Y     |
| P10Y    |
| P0Y     |
| P-50Y   |
| P12Y    |
| P152Y   |
+---------+

I got an exception when trying to use the SUM function against the data:
select sum(cast(columns[1] as interval year)) from `interval_data.csv`;
Error: VALIDATION ERROR: From line 1, column 8 to line 1, column 45: Cannot 
apply 'SUM' to arguments of type 'SUM(<INTERVAL YEAR>)'. Supported form(s): 
'SUM(<NUMERIC>)'

Same error is encountered for same data from JSON file.
This works for interval data from parquet file:
./parquet-schema ../interval_data.parquet
message root {
  optional int32 c_row;
  optional fixed_len_byte_array(12) c_interval_year;
  optional fixed_len_byte_array(12) c_interval_month;
  optional fixed_len_byte_array(12) c_interval_day;
  optional fixed_len_byte_array(12) c_interval_hour;
  optional fixed_len_byte_array(12) c_interval_minute;
  optional fixed_len_byte_array(12) c_interval_second;
  optional binary c_interval (UTF8);
  optional int32 c_time;
  optional int32 c_date;
  optional int64 c_timestamp;
}

select sum(c_interval_year) from `interval_data.parquet`;
+---------+
| EXPR$0  |

| P1692M  |
