Resolution: Fixed
> Expose real-time memory consumption of AM and task containers via DagClient
> ---------------------------------------------------------------------------
>
> Key: TEZ-4339
> URL: https://issues.apache.org/jira/browse/TEZ-4339
> Project: Apache Tez
> Issue Type: Sub-task
> Reporter: László Bodor
> Assignee: László Bodor
> Priority: Major
> Fix For: 0.10.2
>
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> The idea is to simply expose how much memory do all the containers (that
> belong to the current DAG) consume. This info could be very useful for
> developers, or anyone who would want to monitor their applications.
> I'm not yet sure how wasteful this addition would be in terms of client <->
> AM communication, thinking about turning this feature off by default.
