thanks you-all patience help very much??i change the para
spark.yarn.jar spark.yarn.jar
hdfs://master:9000/user/shihj/spark_lib/spark-examples-1.6.1-hadoop2.6.0.jar
to
spark.yarn.jar spark.yarn.jar
hdfs://master:9000/user/shihj/spark_lib/spark-assembly-1.6.1-hadoop2.6.0.jar
then run well??
thanks you-all again??

I cannot get a lot of info from these logs but it surely seems like yarn setup
issue. Did you try the local mode to check if it works -
./bin/spark-submit \
--class org.apache.spark.examples.SparkPi \
--master local[4] \
spark-examples-1.6.1-hadoop2.6.0.jar 10
Note - the jar is a local one

Are you able to run anything else on the cluster, I suspect its yarn that not
able to run the class. If you could just share the logs in pastebin we could
confirm that.

Try providing the jar with the hdfs prefix. Its probably just because its not
able to find the jar on all nodes.
hdfs://master:9000/user/shihj/spark_lib/spark-examples-1.6.1-hadoop2.6.0.jar

spark.yarn.jar(none)The location of the Spark jar file, in case overriding the
default location is desired. By default, Spark on YARN will use a Spark jar
installed locally, but the Spark jar can also be in a world-readable location
on HDFS. This allows YARN to cache it on nodes so that it doesn't need to be
distributed each time an application runs. To point to a jar on HDFS, for
example, set this configuration to hdfs:///some/path.
spark.yarn.jar is used for spark run-time system jar, which is spark assembly
jar, not the application jar (example-assembly jar). So in your case you upload
the example-assembly jar into hdfs, in which spark system jars are not packed,
so ExecutorLaucher cannot be found.
Thanks

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
