----------------------------------
Summary: NettyWorkerAggregatorRequestProcessor tries to reuse
request objects
Key: GIRAPH-839
URL: https://issues.apache.org/jira/browse/GIRAPH-839
Project: Giraph
Issue Type: Bug
Reporter: Pavan Kumar
Assignee: Pavan Kumar
Attachments: GIRAPH-839.patch
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. 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.
