Yin Huai created SPARK-7972:
-------------------------------
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}}..
