Subject What does the -p and -mr option of BuildForest and TestForest mean
Date Sat, 16 Jul 2011 07:26:06 GMT

If call BuildForest without the -p option, then what algorithm is used?

Regarding to the -mr option of TestForest, there are two senarioes:
1. If -i option is supplied with a HDFS file or path URL, will Mahout use Hadoop to do the
classification even if without the -mr option?
2.If -I option is supplied with a local file path, then what does the -mr option will do,
copy the file into the configed Hadoop cluster, or launch a local Hadoop instance?
