Elmer Garduno commented on MAHOUT-1108:
---------------------------------------
Grant, the change works well in both Hadoop and local.
Just a side note: some problems can arise if users had previously used local
mode and the files on the ${WORK_DIR} are still there. This is because the
logic to test for existing files is run locally and the file might actually not
exist on the cluster.
> cluster-reuters.sh executes seqdirectory with MAHOUT_LOCAL=true
