I've followed the instructions in the hadoop definitive guide (also mentioned here How to check memory footprint of Map Task in Hadoop). However, after the task is finished, I can't find any data to look at.

In the book it says that the data is moved to where the client is ran from...I'm using oozie workflow, I wonder where is the hprof data moved to in my case?

The logs are places in the same place as all the other logs. On cloudera dist, I found them on the data node: hadoop.job.history.location
