Spark 2.2.0 Win 7 64 bits Exception while deleting Spark temp dir

[usa usa]

Hi,

I have installed Spark 2.2.0 in win 7 64 bits.

When I did a test:
  c:>run-example SparkPI 10

I got error:
   Exception while deleting Spark temp dir
     C:\Users\jding01\AppData\Local\Temp\spark-xxxxxxx

The solution at

https://stackoverflow.com/questions/31274170/spark-error-error-utils-exception-while-deleting-spark-temp-dir

cannot help me.

Could anyone point out how to fix it ?

Thanks,

David
