Column names in ORC file

Hi,
When I'm generating ORC files using spark the column names are written into
the ORC file but when generated using Hive I get the following column names:

_col107, _col33, _col23, _col102


Is it possible to somehow configure hive to properly store the column
names like Spark?


Thank you,

Daniel

Yes, it was fixed in HIVE-4243.

Possibly related to HIVE-4243 which was fixed in Hive 2.0.0:
