----------------------------

             Summary: SparkContext throws NullPointerException
                 Key: SPARK-6539
                 URL: https://issues.apache.org/jira/browse/SPARK-6539
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.3.0
         Environment: Spark built using the folllowing:
{code}
./make-distribution.sh --tgz -Pyarn -Phadoop-2.2 -Dhadoop.version=2.2.0 -DskipTests
{code}

Targeting Pivotal HD 2.1 (Hadoop 2.2) cluster with the nodes running JDK 8u40
            Reporter: davep


The following snippet of the client driver will throw a NullPointerException when trying to create a SparkContext

{code:java}
SparkConf conf = new SparkConf().setAppName(appName).setMaster("yarn-client");
JavaSparkContext sc = new JavaSparkContext(conf);
{code}

The exception is thrown when trying to create the block manager source here:
https://github.com/apache/spark/blob/branch-1.3/core/src/main/scala/org/apache/spark/SparkContext.scala#L544

If I compile the client driver with JDK7 or JDK8 it throws the same exception. Changing the JDK on the Hadoop cluster resolves this issue.
