> I keep running into this -- with the introduction of Hadoop-2 into the configuration,
if you don't properly set HADOOP_CONF_DIR, you'll get the "default" instance.dfs.uri (I believe)
which will (almost) always not work out for you.
> You get a strange stack trace around ChecksumFileSystem or FilterFileSystem, but the
underlying problem is that your configuration is likely pointing at the wrong configuration
directory for Hadoop ($HADOOP_PREFIX/conf instead of $HADOOP_PREFIX/etc/hadoop, or vice versa).
> We should be able to do something that makes this more intuitive to new-comers with printing
error messages.
