Description

If a table is created externally in hive with struct field names containing upper case letters, selecting the fields of the struct with a '*' fails with the error 'IllegalStateException: Slot paths should be lower case'

Repro:

hive> create table case_test (s struct<FIELD:int>);

impala> invalidate metadata;
impala> select s.* from case_test;
