I tried running spark-1.5.1-bin-hadoop2.6 distribution (and newer versions of Spark with same results) on Windows using Cygwin.
When trying to execute spark-shell script in the bin folder, I get below output:
Error: Could not find or load main class org.apache.spark.launcher.Main
I tried to set CLASSPATH to the location of lib/spark-assembly-1.5.1-hadoop2.6.0.jar but to no avail.
(FYI: I am able to run the same distribution fine on my MAC with no extra setup steps required)
Please assist in finding resolution for Cygwin execution on Windows.
