> LLAP IO supports caching but currently this is only done via LlapRecordReader
> / using splits, aka good old mapreduce way.
> At certain times it would worth to leverage the caching of files on certain
> paths, that are not necessarily associated with a record reader directly. An
> example of this could be the caching of ACID delete delta files, as they are
> currently being read without caching.
> With this patch we'd extend the LLAP API and offer another entry point for
> retrieving metadata of ORC files.
