Giraph should just pick up your cluster's HDFS configuration. Can you
check your hadoop *.xml files?

Hi Everyone,
Not sure why, but Giraph tries to connect to port 9000:
java.net.ConnectException: Call From localhost.localdomain/127.0.0.1
<http://127.0.0.1> to localhost:9000 failed on connection exception:
java.net.ConnectException: Connection refused; For more details see:

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
<http://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?
