    • Added an ability in HOD to start multiple workers (TaskTrackers and/or DataNodes) per node to assist testing and simulation of scale. A configuration variable ringmaster.workers_per_ring was added to specify the number of workers to start.

    Description

      Currently HOD launches at most one slave per node. For purposes of testing a large number of slaves on much fewer resources - for e.g. testing scalability of clusters, it will be useful if it can provision multiple slaves per node.
