>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 2.1.1

> The workers log the spark.ssl.keyStorePassword and 
> spark.ssl.trustStorePassword passed by cli to the executor processes. The 
> ExecutorRunner should escape passwords to not appear in the worker's log 
> files in INFO level. In this example, you can see my 'SuperSecretPassword' in 
> a worker log:
