failure running sparkclr-submit.cmd

I am trying to run a simple spark clr program as local debug mode using VS2012 on my windows environment.

Please find the below steps that i did,

  1. Downloaded v1.6.100 from the following page and extracted to my D drive https://github.com/Microsoft/Mobius/releases

and in my D drive, the folder looks like this, D:\SparkClr\spark-clr_2.10-1.6.100

  1. Set up the following environment variables,
    SPARK_HOME = D:\SparkClr\spark-clr_2.10-1.6.100\runtime
    SPARKCLR_HOME = D:\SparkClr\spark-clr_2.10-1.6.100\runtime
    JAVA_HOME = C:\Program Files\Java\jdk1.8.0_92
    HADOOP_HOME = D:\HadoopDirectory (winutils.exe is present in D:\HadoopDirectory\bin)

  2. Downloaded sparkclr nuget package

In order to set "CSharpBackendPortNumber" in app.config in my local VS program, I need to run in debug mode as per, https://github.com/Microsoft/Mobius/blob/master/notes/running-mobius-app.md#debug-mode

but when i run 'sparkclr-submit.cmd debug' from D:\SparkClr\spark-clr_2.10-1.6.100\runtime\scripts

I am getting the following exception,

D:\SparkClr\spark-clr_2.10-1.6.100\runtime\scripts>sparkclr-submit.cmd debug
'"D:\SparkClr\spark-clr_2.10-1.6.100\runtime\bin\load-spark-env.cmd"' is not rec

Could you please tell me whether i am missing something?

Thanks

Solution

  • SPARK_HOME environment variable should point to Spark directory. You have it pointing to Mobius directory.
