@mateiz I don't think there exists such an input format in standard Hadoop
libraries. This is an example from White's Hadoop book. I see usages like
loading html/xml/json files. If we put it to `SparkContext`, I would still use
the name `wholeTextFile` instead of `textFiles`.
For your second question, we set `isSplittable` to false in
`WholeTextFileInputFormat` to prevent splitting an existing file. Doc says:
> Is the given filename splitable? Usually, true, but if the file is stream
compressed, it will not be. FileInputFormat implementations can override this
and return false to ensure that individual input files are never split-up so
that Mappers process entire files.
But I agree it is worth testing to find out the truth. @yinxusen Can you
create a test for it?
