I have developed a one-liner toolset for Hadoop (when I have to use it). It's fresh to see a ZFS alternate of the concept. Don't like the JavaScript choice though.

GUN parallel should be a widely adopted choice. Lightweight. Fast. Low cost. Extendable.

You can use command-line tools for Manta without touching any Javascript. That's probably the best way to go. Although I do like Javascript.
