----------------------------------------
Summary: Fix broken tests in pseudo-distributed mode
Key: GIRAPH-276
URL: https://issues.apache.org/jira/browse/GIRAPH-276
Project: Giraph
Issue Type: Bug
Reporter: Alessandro Presta
Assignee: Alessandro Presta
As it was pointed out, the following tests are currently broken in
pseudo-distributed mode:
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.
