Rob Vesse updated GIRAPH-795:
-----------------------------
Description:
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:
{noformat}
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 org.apache.giraph.GiraphRunner.run(GiraphRunner.java:96)

at org.apache.hadoop.util.RunJar.main(RunJar.java:212)
{noformat}
When actually in the situations where the NPE is hit Giraph is supposed to be
throwing an informative error message about the need for an external Zookeeper
configuration.
This looks to be a trivial fix for which I will attach a proposed patch
