             Summary: NPE when trying to run Giraph YARN when no Zookeeper configuration is supplied
                 Key: GIRAPH-795
                 URL: https://issues.apache.org/jira/browse/GIRAPH-795
             Project: Giraph
          Issue Type: Bug
    Affects Versions: 1.1.0
            Reporter: Rob Vesse
             Fix For: 1.1.0
         Attachments: GIRAPH-795.patch

If you try and run Giraph compiled for YARN but have not specified any external Zookeeper settings in your Hadoop configuration files you'll receive the following error:

Exception in thread "main" java.lang.NullPointerException
	at org.apache.giraph.yarn.GiraphYarnClient.checkJobLocalZooKeeperSupported(GiraphYarnClient.java:460)
	at org.apache.giraph.yarn.GiraphYarnClient.run(GiraphYarnClient.java:116)

	at java.lang.reflect.Method.invoke(Method.java:597)
	at org.apache.hadoop.util.RunJar.main(RunJar.java:212)

This looks to be a trivial fix for which I will attach a proposed patch
