[GitHub] orc issue #308: Covert tool should create a lowercase schema

Github user omalley commented on the issue:

    https://github.com/apache/orc/pull/308
  
    Actually, this is doesn't match my experience. Hive doesn't support uppercase letters in the top level column names, but it does support them in sub-structs. Furthermore, ORC from other systems can handle the uppercase letters.
    
    You might also try setting "orc.schema.evolution.case.sensitive" to false to get name-based matching of the ORC types that isn't case sensitive.
    
    In terms of this patch, can you add a parameter that allows the user to downcase the column names?
