--------------------------------------------
The test failure is an unrelated flake. It passes for me locally. Will commit
shortly.

> BlockReaderLocal doesn't return -1 on EOF when doing a zero-length read on a
> short file. Specifically, if the file is shorter than the readahead buffer,
> or if the position is nearer to the end than the length of the readahead
> buffer, this may happen. This is mainly a concern because libhdfs relies on
> this to determine whether it should use direct reads.
