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 : 3 11/04/14 23:24:25 INFO mapred.JobClient: Running job: job_201104142306_0001 11/04/14 23:24:26 INFO mapred.JobClient: map 0% reduce 0% 11/04/14 23:24:45 INFO mapred.JobClient: map 66% reduce 0% 11/04/14 23:24:54 INFO mapred.JobClient: map 100% reduce 0% 11/04/14 23:32:50 INFO mapred.JobClient: Task Id : attempt_201104142306_0001_m_000000_0, Status : FAILED Too many fetch-failures 11/04/14 23:32:50 WARN mapred.JobClient: Error reading task outputInvalid argument or cannot assign requested address 11/04/14 23:32:50 WARN mapred.JobClient: Error reading task outputInvalid argument or cannot assign requested address 11/04/14 23:32:54 INFO mapred.JobClient: map 66% reduce 0% 11/04/14 23:33:00 INFO mapred.JobClient: map 100% reduce 0% Can somebody help me to solve this issue.
