> Installing a new cluster can create values in yarn-site.xml which have {{None}} specified in the classpath for Spark

>     </property>
> {code}
> The cause for this is that YARN Clients on hosts without daemons never get a restart command after the initial {{yarn-site.xml}}, and can never fill in the correct values. This causes problems when jobs are run on these nodes:
