             Summary: JobManager should try retrieving jobs from archive
                 Key: FLINK-2388
                 URL: https://issues.apache.org/jira/browse/FLINK-2388
             Project: Flink
          Issue Type: Task
          Components: JobManager
            Reporter: Enrique Bautista Barahona


I was following the quickstart guide with the WordCount example and, when I entered the "analyze" page for the job, nothing came up. Apparently the JobManagerInfoServlet fails with a NullPointerException.

I've been reading the code and I've seen the problem is in the processing of the RequestAccumulatorResultsStringified message in JobManager. There's a TODO where the accumulators should be retrieved from the archive.

As I wanted to know more about Flink internals, I decided to try and fix it. I've later seen that there's currently ongoing work in that part of the code, so I guess maybe it's not needed, but if you want I could submit a PR. If you have already taken it into account and will solve ti shortly, please feel free to close the issue.
