      Hide
      A federation-based approach to transparently scale a single YARN cluster to tens of thousands of nodes, by federating multiple YARN standalone clusters (sub-clusters). The applications running in this federated environment will see a single massive YARN cluster and will be able to schedule tasks on any node of the federated cluster. Under the hood, the federation system will negotiate with sub-clusters ResourceManagers and provide resources to the application. The goal is to allow an individual job to “span” sub-clusters seamlessly.

      Description

      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.
