Hi, Over the past few months I have been writing a tool in Python to ease the pain of editing the CapacityScheduler configuration by hand. Currently, it supports adding, removing, and modifying the properties of queues, adding and removing users, and it performs various sanity checks to ensure that the config will always be well-formed.
I named it Hadmin (I know, so original) and it is on Github at https://github.com/trozamon/hadmin. Hadmin is used to manage a multi-tenant Hadoop cluster at the University of Michigan (http://caen.github.io/hadoop). It's currently in a 'it works for us' beta phase, and I would enjoy others benefiting and testing Hadmin. I'll gladly fix bugs as I have time. It has been primarily developed and tested on RHEL 6.5 and Gentoo. Regards, Alec Ten Harmsel
