> Say we have the following config:
> {code}
> spark.app.name spark shell with spaces and "quotes " and \ backslashes \
> {code}
> This works in standalone mode but not in YARN mode. This is because standalone mode uses
Java's ProcessBuilder, which handles these cases nicely, but YARN mode uses org.apache.hadoop.yarn.api.records.ContainerLaunchContext,
which does not. As a result, submitting an application to YARN with the given config leads
to the following exception:
> {code}
> line 0: unexpected EOF while looking for matching `"'
> syntax error: unexpected end of file
>   at org.apache.hadoop.util.Shell.runCommand(Shell.java:505)
>   at org.apache.hadoop.util.Shell.run(Shell.java:418)
>   at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:650)
>   ...
> {code}
