Lei Guo commented on YARN-3482:
-------------------------------

What's the relationship between this and 3332? They should be considered together.

> NMs are usually collocated with other processes like HDFS, Impala or HBase. To manage
this scenario correctly, YARN should be aware of the actual available resources. The proposal
is to have an interface to dynamically change the available resources and report this to the
RM in every heartbeat.
