Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 1.4.0
Reporter: Herman van Hovell
Support the IntervalType in window range frames, as mentioned in the conclusion
of the databricks blog
[post|https://databricks.com/blog/2015/07/15/introducing-window-functions-in-spark-sql.html]
on window functions.
This actualy requires us to support Literals instead of Integer constants in
Range Frames. The following things will have to be modified:
* org.apache.spark.sql.hive.HiveQl
* org.apache.spark.sql.catalyst.expressions.SpecifiedWindowFrame
* org.apache.spark.sql.execution.Window
* org.apache.spark.sql.expressions.Window
