fileStream
The fileStream creates an input stream that monitors a Hadoop-compatible filesystem. It reads new files using a given key-value type and input format. Any filenames starting with . are ignored. Invoking an atomic file rename function, a filename starting with . is renamed to a usable filename that can be picked up by the fileStream and have its contents processed:
def fileStream[K: ClassTag, V: ClassTag, F <: NewInputFormat[K, V]: ClassTag] (directory: String): InputDStream[(K, V)]
textFileStream
The textFileStream command creates an input stream that monitors a Hadoop-compatible filesystem. It reads new files, as text files with the key as Longwritable, the value as text, and the input format as TextInputFormat. Any files that have names starting with . are ignored:
def textFileStream(directory: String): Dstream[String]
binaryRecordsStream
Using binaryRecordsStream, an input stream that monitors a Hadoop-compatible filesystem  is created. Any filenames starting with . are ignored...
