FAQ
Hi all,

I am running a series of jobs one after another. While executing the
4th job, the job fails. It fails in the reducer --- the progress percentage
would be map 100%, reduce 99%. It gives out the following message

10/04/01 01:04:15 INFO mapred.JobClient: Task Id :
attempt_201003240138_0110_r_000018_1, Status : FAILED
Task attempt_201003240138_0110_r_000018_1 failed to report status for 602
seconds. Killing!

It makes several attempts again to execute it but fails with similar
message. I couldn't get anything from this error message and wanted to look
at logs (located in the default dir of ${HADOOP_HOME/logs}). But I don't
find any files which match the timestamp of the job. Also I did not find
history and userlogs in the logs folder. Should I look at some other place
for the logs? What could be the possible causes for the above error?

I am using Hadoop 0.20.2 and I am running it on a cluster with 14
nodes.

Thank you.

Regards,
Raghava.
