Alessandro Presta created GIRAPH-269:
----------------------------------------
Summary: TestGraphPartitioner is broken and probably not robust
Key: GIRAPH-269
URL: https://issues.apache.org/jira/browse/GIRAPH-269
Project: Giraph
Issue Type: Bug
Reporter: Alessandro Presta
TestGraphPartitioner (distributed-mode only) currently fails with:
{code}
testPartitioners(org.apache.giraph.TestGraphPartitioner) Time elapsed: 65.195
sec <<< FAILURE!
java.lang.AssertionError: expected:<123> but was:<120>
at org.junit.Assert.fail(Assert.java:58)
at org.junit.Assert.failNotEquals(Assert.java:259)
at org.junit.Assert.assertEquals(Assert.java:80)

org.apache.giraph.TestGraphPartitioner.verifyOutput(TestGraphPartitioner.java:59)
at
org.apache.giraph.TestGraphPartitioner.testPartitioners(TestGraphPartitioner.java:96)
{code}
This is most likely due to the serialization changes that came with GIRAPH-244.
The test isn't commented so I can't figure out how we came up with 123 as the
correct number of bytes, but if that depends on the serialization format, then
it's not a robust test.
We should replace the check with something that doesn't depend on bytes count,
or, if impossible, remove the test case.
