How about supplying the jar directly in spark submit - 

./bin/spark-submit \
--class org.apache.spark.examples.SparkPi \
--master yarn-client \
--driver-memory 512m \
--num-executors 2 \
--executor-memory 512m \
--executor-cores 2 \
/user/shihj/spark_lib/spark-examples-1.6.1-hadoop2.6.0.jar

i  config this  para  at spark-defaults.conf

then ./bin/spark-submit --class org.apache.spark.examples.SparkPi --master 
yarn-client --driver-memory 512m --num-executors 2 --executor-memory 512m 
--executor-cores 2    10:
