IMPALA-5994: Failure in star expansion on struct fields
Impala tries to always store column names in lower case. As part of a
cleanup of issues related to upper case Kudu column names, a check was
added in Analyzer to enforce this.
The check fails when doing star expansion on a struct to select all
fields in the case where a table was created in Hive with upper case
letters in a struct field name. This happens because Hive does not
covert struct field names to all lower case in HMS.
The solution is to force StructField names to lower case.
Testing:
- Added a test in test_nested_types.py
