Hello friends, I am new to Apache MapReduce. I just wrote a program that processes 89 files, each of which is 10000 lines. The program runs a clustering algorithm of the contents of the 89 files. The job failed a couple of times before it was terminated without any results wrote to the output folder.
Here is the logs printer on the console: 12/01/18 15:27:54 INFO input.FileInputFormat: Total input paths to process : 88 12/01/18 15:27:59 INFO mapred.JobClient: Running job: job_201201121550_0055 12/01/18 15:28:00 INFO mapred.JobClient: map 0% reduce 0% 12/01/18 15:28:19 INFO mapred.JobClient: map 1% reduce 0% 12/01/18 15:28:40 INFO mapred.JobClient: map 2% reduce 0% 12/01/18 15:32:46 INFO mapred.JobClient: map 3% reduce 0% 12/01/18 15:42:50 INFO mapred.JobClient: map 2% reduce 0% 12/01/18 15:42:52 INFO mapred.JobClient: Task Id : attempt_201201121550_0055_m_000002_0, Status : FAILED Task attempt_201201121550_0055_m_000002_0 failed to report status for 602 seconds.

Please let me know if you have any answers for me. Thanks very much, -Ahmed
