--------------------------------------
Hm, looks like the build failed because a test couldn't connect to ZooKeeper?

> NettyWorkerAggregatorRequestProcessor tries to reuse request objects

> Key: GIRAPH-839
> URL: https://issues.apache.org/jira/browse/GIRAPH-839

>
> I was working on upgrading netty to 4.0.14.Final. It is mostly done, after
> some polishing I will submit a patch for that soon.
> While working on the above, I discovered a bug in
> NettyWorkerAggregatorRequestProcessor. The distributeAggregators method is
> reusing SendAggregatorsToWorkerRequest objects, which is incorrect since each
> task has a different task id & (potentially a different) request id. It does
> not cause any problem with current netty but in the new version I guess due
> to delayed serialization the object cannot be reused.
> Anyway, moving it inside the for loop does not cause any issues with current
> netty as well.
