----------------------------------
Summary: disallow change of column name when talbe's serde is
parquet serde
Key: HIVE-6770
URL: https://issues.apache.org/jira/browse/HIVE-6770
Project: Hive
Issue Type: Task
Affects Versions: 0.13.0
Reporter: Tongjie Chen
hive column is index based, hence changing column name does not affect the
result.
However parquet columns are name based, changing column will result in
incorrect result.
Before rename issue is addressed in parquet, hive should disallow column rename
if Parquet is used.
