i have created vector dir , programme delets dir , fails exception filenotfound .

can please help resolving issue .

thanks :)

mahout running on distributed file scheme instead of local file scheme on default. when run mahout command, hadoop seek find files on hdfs instead of on local. thus, should follows:

cd mahout/bin directory vi mahout find line "#mahout_local=true;" , alter "mahout_local=true;" source mahout

then should work on local now.

hadoop mahout
