No, there are no log entries for this job. It seems that the job failed
before starting the logs.
Another thing: there was a typo in the code:
It should be job.setOutputValueClass(Text.class); in the code.
It doesn't make a difference though.

Dear fellow Hama users,
It seems that FileInputFormat.setInputPaths doesn't work correctly
for multiple HDFS paths (although it works fine in local mode
using local files). I am using Hama 0.5.0 on Hadoop 1.0.3.
I am attaching a simple code that concatenates text form files
(just to show the error).
It works fine in local mode for multiple files, it works fine in
pseudo-distributed mode for just one file, but it doesn't work in
pseudo-distributed mode on multiple HDFS files: it displays the
following with no entry in the log for this job:
&&&

12/07/28 09:42:00 INFO bsp.BSPJobClient: Running job:

12/07/28 09:42:03 INFO bsp.BSPJobClient: Job failed.
Both paths are correct and can be accessed separately.
Is this a Hama error or am I doing something wrong?
Thanks for your help,
