seqdirectory error on mapreduce

[pzhang <pz...@sandia.gov>]

My set-ups seems work well:
$hadoop fs –copyFromLocal reuters_text reuters_text
$hadoop fs –ls reuters_text/
                Many files in the directory
                
$mahout seqdirectory –i reuters_text –o reuters_seq –c UTF-8

                reuters_seq directory generated but empty

mapreduce job was failed with the message:

Some suggestions?
                
I am running hadoop2.2.0, mahout 0.8.

Thanks.
