> ALTER INDEX TestTableA_IDX ON TestTable REBUILD;

> When you execute: "SHOW INDEXES ON TestTable;", you get:
> TestTableA_IDX      	testtable           	a                   	default__testtable_testtablea_idx__	compact
> so it looks like things don't get lower cased when they go into the metastore, but they do when the rebuild op is trying to execute.
