After spending the better part of a day trying to get HDFS to mount on my Mac, I finally gave up. Luckily, I was able to find MuCommander, a cross-platform Java port of the Norton Commander of old, and as luck would have it, it supports HDFS in the latest version! Very handy for quickly browsing your HDFS clusters if you can’t mount it or don’t have the Hadoop toolset installed.
