When I execute the following in yarn-client mode its working fine and giving the result properly, but when i try to run in Yarn-cluster mode i am getting error

spark-submit --class org.apache.spark.examples.SparkPi --master yarn-client /home/abc/spark/examples/lib/spark-examples_2.10-1.0.0-cdh5.1.0.jar 10

 The above code works fine, but when i execute the same code in yarn cluster mode i amgetting the following error.
