Hi, When I run the itembased recommendation using hadoop, there is no fetch failure in the prePartialMultiply2. But when I use 2 nodes, there is a fetch failure in the prePartialMultiply2. ****hdfs://master:54310/user/hduser3/temp/prePartialMultiply1,hdfs://master:54310/user/hduser3/temp/prePartialMultiply2 13/07/01 15:32:44 INFO input.FileInputFormat: Total input paths to process : 2 13/07/01 15:32:44 INFO mapred.JobClient: Running job: job_201307011502_0009 13/07/01 15:32:45 INFO mapred.JobClient: map 0% reduce 0% 13/07/01 15:32:59 INFO mapred.JobClient: map 50% reduce 0% 13/07/01 15:33:02 INFO mapred.JobClient: map 86% reduce 0% 13/07/01 15:33:05 INFO mapred.JobClient: map 100% reduce 0% 13/07/01 15:33:08 INFO mapred.JobClient: map 100% reduce 16% 13/07/01 15:33:55 INFO mapred.JobClient: Task Id : attempt_201307011502_0009_m_000000_0, Status : FAILED Too many fetch-failures 13/07/01 15:33:55 WARN mapred.JobClient: Error reading task outputhttp://localhost:50060/tasklog?plaintext=true&attemptid=attempt_201307011502_0009_m_000000_0&filter=stdout 13/07/01 15:33:55 WARN mapred.JobClient: Error reading task outputhttp://localhost:50060/tasklog?plaintext=true&attemptid=attempt_201307011502_0009_m_000000_0&filter=stderr 13/07/01 15:33:59 INFO mapred.JobClient: map 50% reduce 16% 13/07/01 15:34:05 INFO mapred.JobClient: map 85% reduce 16% 13/07/01 15:34:08 INFO mapred.JobClient: map 100% reduce 16% 13/07/01 15:34:20 INFO mapred.JobClient: map 100% reduce 33% 13/07/01 15:34:26 INFO mapred.JobClient: map 100% reduce 100%
How to remove this failure. Thanking you, Neetha Susan Thampi
