> If {{cdc_raw_directory}} is set to an invalid directory it prevents startup of the server even when cdc_enabled is set false.
> The directory can either be set directly by the {{cdc_raw_directory}} setting in configuration YAML or indirectly via the {{cassandra.storage_dir}} system property, which is how I encountered it.
> Easy to reproduce by setting {{cdc_raw_directory}} to {{notadir/notasubdir}}
> Additionally while investigating, discovered that {{DatabaseDescriptor.guessFileStore}} can cause a {{NullPointerException}} if it runs out of parent elements
>  before it can get a FileStore. It should provide a more useful ConfigurationException providing details on the problematic path.
>  {{guessFileStore}} is used for checks on {{commitlog_directory}}, {{cdc_raw_directory}} and {{data_file_directories}}.
