To reproduce your exception, I submitted a Pi example(https://github.com/Microsoft/SparkCLR/tree/master/examples/pi) to yarn cluster with following cmd:
scripts\sparkclr-submit.cmd --verbose --master yarn-cluster --exe Pi.exe ..\Pi.zip
Unfortunately I can't reproduce it. Please double check the environment variables including SPARK_HOME, HADOOP_HOME and make sure they are set properly, and the configuration items are also consistent with the yarn cluster your application will be submitted to.
SparkContext = new SparkContext("yarn-cluster", "PiExample")to instantiate the sparkcontext.

Hi Kaarthik. I just cloned your Git repo. I am not really a Spark developer, so my question might be fairly elemental. I got everything building, and the unit tests run just fine. What I want to do is debug the Pi sample from within Visual Studio 2015. I first opened up a Visual Studio Developer's Command Prompt and as per your debug instructions, ran the command "sparkclr-submit.cmd debug". I got the message "[CSharpRunner.main] Backend running debug mode. Press enter to exit" .... so far, so good. Then, I opened the SparkCLR.sln solution in Visual Studio, set the startup program to the "Samples" project, and in the project properties, I set the arguments to "--torun pi*". I then started the debug session. After the 300,000 integer array was initialized, I got these errors:
JVM method execution failed: Static method collectAndServe failed for class org.apache.spark.api.python.PythonRDD when called with 1 parameters ([Index=1, Type=JvmObjectReference, Value=13], )
org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 0.0 failed 1 times, most recent failure: Lost task 0.0 in stage 0.0 (TID 0, localhost): java.net.SocketException: Connection reset by peer: socket write error
Do you have any idea? I am sure that I need to set some jar file path or class path somewhere.
