davep created SPARK-6539:
----------------------------
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.
