[jira] [Created] (FLINK-2152) Provide zipWithIndex utility in flink-contrib

Robert Metzger created FLINK-2152:
-------------------------------------

             Summary: Provide zipWithIndex utility in flink-contrib
                 Key: FLINK-2152
                 URL: https://issues.apache.org/jira/browse/FLINK-2152
             Project: Flink
          Issue Type: Improvement
          Components: Java API
            Reporter: Robert Metzger
            Priority: Trivial


We should provide a simple utility method for zipping elements in a data set with a dense index.
its up for discussion whether we want it directly in the API or if we should provide it only as a utility from {{flink-contrib}}.

I would put it in {{flink-contrib}}.
