I followed this page and ran the SparkPi example application on YARN in yarn-cluster mode.
http://spark.apache.org/docs/latest/running-on-yarn.html
I don't see the output of the program at the end (which is the result of the computation in this case). When I run it in the yarn-client mode (--master yarn-client), I see an output like this:
Pi is roughly 3.138796
Where does the standard out go in the yarn-cluster mode?
