Hi all, I am having trouble running the hello-samza example ( http://samza.apache.org/learn/tutorials/0.10/run-in-multi-node-yarn.html) on our HDP cluster, which is set up with Ambari.
Upon running *deploy/samza/bin/run-job.sh --config-factory=org.apache.samza.config.factories.PropertiesConfigFactory --config-path=file://$PWD/deploy/samza/config/wikipedia-feed.properties* The output shows that Samza keeps trying to reach YARN's ResourceManager at *0.0.0.0:8032 <http://0.0.0.0:8032>* but can't. *2016-02-25 01:28:00 ClientHelper [INFO] trying to connect to RM 0.0.0.0:8032 <http://0.0.0.0:8032>* *2016-02-25 01:28:00 RMProxy [INFO] Connecting to ResourceManager at /0.0.0.0:8032 <http://0.0.0.0:8032>* *2016-02-25 01:28:00 NativeCodeLoader [WARN] Unable to load native-hadoop library for your platform... using builtin-java classes where applicable* *2016-02-25 01:28:02 Client [INFO] Retrying connect to server: 0.0.0.0/0.0.0.0:8032 <http://0.0.0.0/0.0.0.0:8032>.

Can anyone help? Thanks, Jack Huang
