Giraph keeps trying to connect to 9000 on Hadoop 2.2.0/YARN

[John Yost]

Hi Everyone,

Not sure why, but Giraph tries to connect to port 9000:

java.net.ConnectException: Call From localhost.localdomain/127.0.0.1 to
localhost:9000 failed on connection exception: java.net.ConnectException:
Connection refused; For more details see:
http://wiki.apache.org/hadoop/ConnectionRefused
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

I set the following in the Giraph configuration:

      GiraphConstants.IS_PURE_YARN_JOB.set(conf,true);
      conf.set("giraph.useNetty","true");
      conf.set("giraph.zkList","localhost.localdomain");
              conf.set("fs.defaultFS","hdfs://localhost.localdomain:8020")
      conf.set("mapreduce.job.tracker","localhost.localdomain:54311");
      conf.set("mapreduce.framework.name","yarn");
      conf.set("yarn.resourcemanager.address","localhost.localdomain:8032");

I built Giraph as follows:

mvn -DskipTests=true -Dhadoop.version=2.2.0 -Phadoop_yarn clean install

Any ideas as to why Giraph attempts to connect to 9000 instead of 8020?
