László Bodor updated TEZ-4339:
------------------------------
Description:
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.
> Expose real-time memory consumption of AM and task containers via DagClient
