> The metadata path of ozone container should be checked properly and created 
> accordingly while it's initiated. Some code snips that we need to change are 
> here:
> {{ContainerMapping.java}}
> {code}
>     // TODO: Fix this checking.
>     String scmMetaDataDir = conf.get(OzoneConfigKeys
>         .OZONE_CONTAINER_METADATA_DIRS);
>     if ((scmMetaDataDir == null) || (scmMetaDataDir.isEmpty())) {
>       throw
>           new IllegalArgumentException("SCM metadata directory is not 
> valid.");
>     }
> {code}
> {{OzoneContainer.java}}
> {code}
>     List<StorageLocation> locations = new LinkedList<>();
>     String[] paths = ozoneConfig.getStrings(
>         OzoneConfigKeys.OZONE_CONTAINER_METADATA_DIRS);
>     if (paths != null && paths.length > 0) {
>       for (String p : paths) {
>         locations.add(StorageLocation.parse(p));
>       }
>     } else {
>       getDataDir(locations);
>     }
> {code}
