Isabel Drost commented on MAHOUT-916:
-------------------------------------
Unfortunately it isn't quite as easy - Hadoop sets that system property to pass
configured temporary directories to a job. The variable to set is
hadoop.tmp.dir. Currently adjusting our unit tests to pass a configuration down
to Hadoop jobs that includes this setting.
In that process I came across a few drivers that do not pass a configuration
object down to sub-jobs spawned (which means that user supplied options will
not be taken into account for these sub jobs) - will open a separate issue for
these.
