We generally want to update to the latest Hadoop 2.7.x, but had an issue
with 2.7.7 and reverted. Here I wanted to go ahead and link to the latest
anyway, but for some reason this doc was only in the 2.7.6 docs, not 2.7.7. I
doubt the doc will actually vary non-trivially from version to version, but
wanted to at least point at a 2.7.x version.
