-------------------------------

             Summary: When parse window spec frame, we need to do case 
insensitive matches.
                 Key: SPARK-7972
                 URL: https://issues.apache.org/jira/browse/SPARK-7972
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.4.0
            Reporter: Yin Huai
            Assignee: Yin Huai


For window frame, PRECEDING, FOLLOWING, and CURRENT ROW do not have pre-defined 
tokens. So, Hive Parser returns the user input directly (e.g. {{preCeDING}}). 
We need to do case insensitive matches in {{HiveQl.scala}}..
