----------------------------------
Hi, Leting Wu, did you solve the problem? I meet the some error as yours. I use
Hadoop1.0.1 and Mahout0.7 in Ubuntu1204 as namenode and 2 Ubuntu1010 as
datanodes.
I executed the classify-20newsgroups.sh step by step. It failed when I go to
step "./bin/mahout trainnb", the same error info as yours.
I must run in a hadoop cluster environment. I think it's the 'trainnb' command
issue. Any body help me?
