----------------------------------------------
Summary: Selecting same column with different case from a parquet
file results in just one column returned
Key: DRILL-2298
URL: https://issues.apache.org/jira/browse/DRILL-2298
Project: Apache Drill
Issue Type: Bug
Components: Storage - Parquet
Affects Versions: 0.8.0
Reporter: Ramana Inukonda Nagaraj
Assignee: Steven Phillips
When selecting the same column twice with the same case everything works as
expected.
{code}
0: jdbc:drill:> select BIGINT_col,BIGINT_col from
`parquet_storage/parquet_all_types.parquet` limit 1;
+------------+-------------+
| BIGINT_col | BIGINT_col0 |
+------------+-------------+
| 1 | 1 |
+------------+-------------+
1 row selected (0.086 seconds)
{code}
However, when different case is used for the same column only one column is
returned.
{code}
0: jdbc:drill:> select BIGINT_col,bigint_col from
`parquet_storage/parquet_all_types.parquet` limit 1;
+------------+
| BIGINT_col |
+------------+
| 1 |
+------------+
1 row selected (0.079 seconds)
