Dictionary file cannot be found error

[Huanchen Zhang]

Hi,

After I've done the LDA topic analysis. I want to obtain the output of the 
topics using :

bin/mahout ldatopics \
    -i <input vectors directory> \
    -d <input dictionary file> \
    -o <optional output working directory. Default is to console> \
    -dt <optional dictionary type (text|sequencefile). Default is text>

But, it always tells me the dictionary file cannot be found:

Exception in thread "main" java.io.FileNotFoundException:

But, I can see the dictionary file is there in HDFS using hadoop fs -ls.

Anyone has any ideas ? Thank you very much !

Best,
