taegeonum opened a new pull request #123: [NEMO-129] Support Beam's WindowedWordCount example
URL: https://github.com/apache/incubator-nemo/pull/123
 
 
   JIRA: [NEMO-129: Support Beam's WindowedWordCount example](https://issues.apache.org/jira/projects/NEMO/issues/NEMO-129)
   
   **Major changes:**
   - Change `GroupByKeyTransform` to group elements according to the key and window. Use `GroupAlsoByWindowViaWindowSetNewDoFn` that is a wrapper class for group by key and window in beam. 
   
   **Minor changes to note:**
   - refactor `DoFnTransform` and create `AbstractTransform` to reuse codes in both `DoFnTransform` and `GroupByKeyTransform`
   
   **Tests for the changes:**
   - test windowed word count (fixed window and sliding window) 
   
   **Other comments:**
