When I start the spark-yarn using this command "spark-shell --master yarn-client" Im getting an error saying:
<code>ERROR spark.SparkContext: Error initializing SparkContext.
java.lang.NullPointerException
The full error I got in starting spark shell with yarn is below, the logs about yarn containers is here:
<code>Container: container_1463670715317_0002_01_000001 on masternode_52694
