##Solving a Spark error: Invalid signature file digest for Manifest main attributes
When using spark-submit to run a jar, you may encounter this error:
Invalid signature file digest for Manifest main attributes
The error occurs when one of the included libraries in the jar's META-INF directory has a bad signature.
Solve the error with this command:
zip -d <jar file name>.jar META-INF/*.RSA META-INF/*.DSA META-INF/*.SF
It works like a charm!!
