Samuel Yuan created HIVE-4344:
---------------------------------
Summary: CREATE VIEW fails when redundant casts are rewritten
Key: HIVE-4344
URL: https://issues.apache.org/jira/browse/HIVE-4344
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.11.0
Reporter: Samuel Yuan
Assignee: Samuel Yuan
e.g. create view v as select cast(key as string) from src;
The rewriter tries to replace both cast(key as string) and key as `src`.`key`,
because cast(key as string) is a no-op.
There may be other cases like this one.
