Spark-shell not started in windows 8

I have downloaded the spark1.6 version & unzipped the same in the local E drive in my windows 8 system. After I have copy the spark path until bin folder & pasted in the environment variables in the
system variables where I edit the path with semicolon ;add the path there.

When I stared the spark-shell in the command prompt it says “‘cmd’ is not recognized as an internal or external command…”.

Anyone facing the same issue.

Note:
Already installed scala version 2.11 and java 8 in the system successfully by checked in command prompt.

@smileanbu13 Before that can you check whether are you able to invoke the spark-shell from /bin/spark-shell
