Subject RE: Error when executing a WordCount Program
Date Wed, 10 Sep 2014 13:54:25 GMT

In fact,

is not a folder on hdfs.

I created a folder /tmp/hadoop-hadoop/dfs/data, where data will be saved in hdfs.

And in my HADOOP_HOME folder, there is two folders “input” and “output”, but I don’t
know how to configure them in the program.

Please could you look into my code and advise please ?

Standing by …

Warm regards

is this is a valid path on hdfs? Can you access this path outside of the program? For example
using hadoop fs -ls command? Also, was this path and files in it, created by a different user?

The exception seem to say that it does not exist or the running user does not have permission
to read it.
