> When specifying paths in the *-site.xml files, some are required to be fully qualified, while others (specifically hadoop.tmp.dir) break when a fully qualified uri is used.
> Example:
> If I set hadoop.tmp.dir in core-site to file:///something it'll create a file: directory in my $PWD.

>   <property>
>     <name>hadoop.tmp.dir</name>
>     <value>file:///grid/a/tmp/hadoop-${user.name}</value>
>   </property>

> └── grid
>     └── a
>         └── tmp
>             └── hadoop-tthompso

> Other places, like the datanode, or the nodemanager, will complain if I don't use fully qualified uris
