This is supposed to be a generic option. You should be able to specify Hadoop options such as this on the command line invocation of your favorite Mahout routine, but I'm having a similar problem setting -Dmapred.reduce.tasks=10 with Canopy and k-Means. This is both with and without a space after the -D.
Can someone point me to a Mahout command where this does work? Both drivers extend AbstractJob and do the usual option processing pushups. I don't have Hadoop source locally so I can't debug the generic options parsing. -----Original Message----- From: beneo_7 [mailto:[email protected]] Sent: Monday, December 27, 2010 10:45 PM To: [email protected] Subject: where i can set -Dmapred.map.tasks=X i read onMahout in Action that I should set -Dmapred.map.tasks=X but it did not work for hadoop
