spark slave cannot execute without admin permission on windows

[Judy Nash]

Hi,

Is it possible to configure spark to run without admin permission on windows?

My current setup run master & slave successfully with admin permission.
However, if I downgrade permission level from admin to user, SparkPi fails with 
the following exception on the slave node:
Exception in thread "main" org.apache.spark.SparkException: Job aborted due to s
tage failure: Task 0 in stage 0.0 failed 4 times, most recent failure: Lost task
0.3 in stage 0.0 (TID 9, workernode0.jnashsparkcurr2.d10.internal.cloudapp.net)
: java.lang.ClassNotFoundException: org.apache.spark.examples.SparkPi$$anonfun$1

        at java.lang.Class.forName(Class.java:270)

Upon investigation, it appears that sparkPi jar under 
spark_home\worker\appname\*.jar does not have execute permission set, causing 
spark not able to find class.

Advice would be very much appreciated.

Thanks,
Judy
