> ParallelFileMetadataLoader.loaders_ became a Map, but at one place we still treat it as a List:
> {noformat}
> LOG.error(logPrefix_ + " encountered an error loading data for path " + loaders_.get(i).getPartDir(), e);
> {noformat}
> 'i' is an integer, while the loaders_'s key type is Path.
> Unfortunately the code compiles which means we get a NullPointerException for this statement.
