Github user spmallette commented on the issue: https://github.com/apache/tinkerpop/pull/801 I'm sorry to say that spark integration tests are failing for your added tests. Not sure what's wrong. I made an initial fix that solved the first body of errors. I updated `ToyGraphInputRDD` to include: ```java else if (configuration.getString(Constants.GREMLIN_HADOOP_INPUT_LOCATION).contains("sink")) vertices = IteratorUtils.list(IteratorUtils.map(TinkerFactory.createKitchenSink().vertices(), VertexWritable::new)); ``` But the tests still fail with: ```text [ERROR] testMessagePassingOut(org.apache.tinkerpop.gremlin.process.computer.GraphComputerTest) Time elapsed: 5.693 s <<< ERROR! java.util.concurrent.ExecutionException: java.lang.IllegalStateException: Name is null at org.apache.tinkerpop.gremlin.process.computer.GraphComputerTest.runMPTest(GraphComputerTest.java:2741) at org.apache.tinkerpop.gremlin.process.computer.GraphComputerTest.testMessagePassingOut(GraphComputerTest.java:2710) Caused by: java.lang.IllegalStateException: Name is null Caused by: java.lang.NullPointerException: Name is null [ERROR] testMessagePassingBoth(org.apache.tinkerpop.gremlin.process.computer.GraphComputerTest) Time elapsed: 5.397 s <<< ERROR! java.util.concurrent.ExecutionException: java.lang.IllegalStateException: Name is null at org.apache.tinkerpop.gremlin.process.computer.GraphComputerTest.runMPTest(GraphComputerTest.java:2741) at org.apache.tinkerpop.gremlin.process.computer.GraphComputerTest.testMessagePassingBoth(GraphComputerTest.java:2726) Caused by: java.lang.IllegalStateException: Name is null Caused by: java.lang.NullPointerException: Name is null [ERROR] testMessagePassingIn(org.apache.tinkerpop.gremlin.process.computer.GraphComputerTest) Time elapsed: 5.198 s <<< ERROR! java.util.concurrent.ExecutionException: java.lang.IllegalStateException: Name is null at org.apache.tinkerpop.gremlin.process.computer.GraphComputerTest.runMPTest(GraphComputerTest.java:2741) at org.apache.tinkerpop.gremlin.process.computer.GraphComputerTest.testMessagePassingIn(GraphComputerTest.java:2694) Caused by: java.lang.IllegalStateException: Name is null Caused by: java.lang.NullPointerException: Name is null ``` Not sure I know what is causing that....I don't what "Name" is referring to here. I was guessing the property you just added to "sink" but it's not the same case, so......
