Re: is RM require a lot of memory?
Remember that in YARN, the two main responsibilities of the JobTracker is
divided in two different components:
- Resource Management by ResourceManager (this is a global component)
- Job scheduling and monitoring by the NodeManager (this is a per-node
component)
- Resource negotiation and task execution by the ApplicationMaster (which
it´s a per-application component)

Said this, like any Java-based process, for YARN could be very beneficial
to have a lot of RAM in a careful tuned JVM.
