Subject Error : Too many fetch-failures
Date Thu, 14 Apr 2011 10:12:40 GMT
Hello,

I am new to hadoop.
I am using hadoop 0.20.2 on ubuntu.

I recently installed and configured hadoop using the available tutorials on
internet.
My hadoop is running properly.

But Whenever I am trying to run a wordcount example, the wordcount program
got stuck at the reduce part. After long time , I am getting the following
error..

hadoop@50:/usr/local/hadoop/hadoop$ hadoop jar hadoop-0.20.2-examples.jar
wordcount gutenberg gutenberg-output
11/04/14 23:24:20 INFO input.FileInputFormat: Total input paths to process :

11/04/14 23:33:00 INFO mapred.JobClient:  map 100% reduce 0%

Can somebody help me to solve this issue. Its urgent.. I wasted my whole day
in figuring out the problem.

Thanks,
Praveenesh
