How to fix “Task attempt_201104251139_0295_r_000006_0 failed to report status for 600 seconds.”

Question

I wrote a mapreduce job to extract some info from a dataset. The dataset is users\' rating about movies. The number of users is about 250K and the number of movies is about 300k

Answer 1

The easiest another way is to set in your Job Configuration inside the program

 Configuration conf=new Configuration();
 long milliSeconds = 1000*60*60; 

**before setting it please check inside the Job file(job.xml) file in jobtracker GUI about the correct property name whether its mapred.task.timeout or mapreduce.task.timeout . . . while running the job check in the Job file again whether that property is changed according to the setted value.
