----------------------------------
Thanks [~subru] and [~curino]. This is very relevant to us at Uber since we
also run multiple YARN clusters across multiple data centers.

> This is an umbrella JIRA that proposes to scale out YARN to support large
> clusters comprising of tens of thousands of nodes. That is, rather than
> limiting a YARN managed cluster to about 4k in size, the proposal is to
> enable the YARN managed cluster to be elastically scalable.
