> Fix broken tests in pseudo-distributed mode
> -------------------------------------------
>                 Key: GIRAPH-276
>                 URL:
>             Project: Giraph
>          Issue Type: Bug
>            Reporter: Alessandro Presta
>            Assignee: Alessandro Presta
>         Attachments: GIRAPH-276.patch
> As it was pointed out, the following tests are currently broken in pseudo-distributed
> 1) testBspPageRank, testBspPageRankWithAggregatorWriter
> These have been broken for a long time AFAIK, and are due to errors in aggregators. Maja's
patch (GIRAPH-259) fixes them, so I won't address them here.
> 2) TestMutateGraphVertex
> After GIRAPH-244, Edge doesn't implement Writable anymore. Unfortunately, there was a
sneaky place where it was still required: when using Hadoop RPC, BasicRPCCommunications#addEdge()
on the server is called through a proxy, and its parameters are expected to be Writable. A
simple signature change fixes this.
> 3) TestGraphPartitioner
> I opened GIRAPH-269 on this one. I don't know how we got to the hardcoded number of expected
bytes (123), but if that was obtained by running the test itself, then it's not a great test.
> For now, I'm simply changing that to 120, which is what we get after the serialization
changes in EdgeListVertex, but I'm leaving GIRAPH-269 open since we should replace this with
something more robust.
> I added a TODO comment so we don't forget it.
