Hadoop node manager does not satisfy minimum alloc

Question

Hadoop node manager doesn't satisfy minimum allocations. I am getting the following error:

org.apache.hadoop.yarn.exceptions.YarnRuntimeException: Received SHUTDOWN signal from Resourcemanager, Registration of NodeManager failed, Message from Resource Manager: NodeManager from DP112.Mas.company.com doesn't satisfy minimum allocations, Sending SHUTDOWN signal to the NodeManager.

RAM -6 GB in my physical box And I am setting Single node setup for initial testing purpose

Answer 1

The "ResourceManager: NodeManager from *** doesn't satisfy minimum allocations" error is seen when node on which node manager is being started does not have enough resources w.r.t yarn.scheduler.minimum-allocation-vcores and yarn.scheduler.minimum-allocation-mb configurations.

Reduce values of yarn.scheduler.minimum-allocation-vcores and / or yarn.scheduler.minimum-allocation-mb then restart Yarn.
