Thanks Vinod. Yes it's the second case where I am working with MR over yarn.
When I run a job then for a specific Machine I am trying to compute that
how much time the machine takes to execute mapping tasks and reduce tasks.
What I am doing now is that I compute time difference between container
a
Moving to yarn-dev, as that is the right place for this discussion.
Can you let us know more about what you are trying to accomplish? Working with
MapReduce over YARN or your own YARN application?
If you are working with MR over YARN, you have to note that
TaskId/TaskAttemptID/Map/Reduce task
There really is no way. The RM also has no knowledge of map tasks vs
reduce tasks nor should it know.

Container, Application and Request in ResourceManager, can I somehow get
TaskId by using any of these objects?? Please let me know a way.
Thanks.
