paragraph 3: link [3] should be to the 1.6 version of the bulk ingest information.
paragraph 5-7: It would be nice if you could show some kind of chart to back up the NameNode having scale issues. you could cite the usenix article from 2010 on NameNode write rates[1], but that was only like 6k/sec and was really only close to the needed "create new file" and not rename, move, or delete. You could try to use NNThroughputBenchmark to atleast update that stat on modern hardware. I don't know if it also includes anything for the other ops. paragraph 9: I'd recommend rephrasing the bit about HDSF federation being insufficient for Accumulo. Accumulo could have found other approaches to leverage Federation as is, but would have been awkward to use on anything other than a per-table level. We can showcase MVS as a way to leverage federation easily within Accumulo rather than as an alternative approach. Honestly, the only way I expect MVS to be feasibly deployed is with federation used to name several accumulo data directories in a single namespace. Federation handles sharing datanodes across all the namenodes you configure. Unless you want to give up things like short circuit reads, we'll either need more infra to associate tservers with particular volumes or we'll need to run multiple datanode processes per host. It'll be messy. paragraph 17: Is there any chance that this example configuration could be presented as a set of docker or vagrant nodes that are configured to run an example cluster with multiple hdfs instances and Accumulo with MVS enabled? Something people can poke at will be way more popular than XML configs as they are. If you don't have more time to polish, I understand. In that case the blog post will read better if the scripts are in a github repo and linked from the article (possibly with an embedded preview if github does that sort of thing.) My apologies if it's formatted differently on the actual preview. My request for a roller account hasn't gotten anywhere yet.
