reads, which differs from the more common full file read used in most

sentences.
If we're adding clarifications, I would also suggest adding a note about
what the "version specified in the pom" actually means. I'm positive that
normal users don't understand all of the implications. What about a third
point..
"The versions set in the pom for Hadoop and ZooKeeper are treated as stable
releases which provide a large-breadth of compatibility across other versions
of those components. They do not guarantee compatibility with any other
versions because Hadoop and ZooKeeper do not provide any such guarantee."
