Find the task and it's datanode which is taking the most time in a cluster
Hi,
Can somebody please help me how to find the task and the datanode in a
large cluster which has failed or which is taking the most time to execute
considering thousands of mappers and reducers are running.

Shashi

Hi Shashi,
I am assuming that you are running hadoop 1.x. There is an option to see
the failed tasks on the Job tracker UI. Please replace the jobtracker host
with the actual host and click on the following link and look for the task
failure.

Thanks
