davep updated SPARK-6539:
-------------------------
Description:
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 to v7 resolves this issue.
