Enrique Bautista Barahona updated FLINK-2388:
---------------------------------------------
Description:
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 it shortly, please feel free
to close the issue.
