Where is the hadoop task's hprof data stored when using oozie workflow - measuring memory usage

Question

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?

Answer 1

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
