Hadoop uses the following path filter (FileInputFormat.hiddenFileFilter): ```Java private static final PathFilter hiddenFileFilter = new PathFilter() { public boolean accept(Path p) { String name = p.getName(); return !name.startsWith("_") && !name.startsWith("."); } }; ``` Since SparkContext.textFile uses `TextInputFormat`, it uses this filter and ignores files that start with "-" or ".". Should Streaming be consistent with Core?
