> 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 $PWD.
> {noformat}
> <property>
> <name>hadoop.tmp.dir</name>
> <value>file:///grid/a/tmp/hadoop-${user.name}</value>
> </property>
> {noformat}
> {noformat}
> [tthompso@test ~]$ tree file\:/
> file:/
> └── grid
> └── a
> └── tmp
> └── hadoop-tthompso
> {noformat}
> Other places, like the datanode, or the nodemanager, will complain if I don't
> use fully qualified uris
> {noformat}
