Container for the parameters to the SetUnhealthyNodeReplacement operation.
Specify whether to enable unhealthy node replacement, which lets Amazon EMR gracefully
replace core nodes on a cluster if any nodes become unhealthy. For example, a node
becomes unhealthy if disk usage is above 90%. If unhealthy node replacement is on
and TerminationProtected are off, Amazon EMR immediately terminates the unhealthy
core nodes. To use unhealthy node replacement and retain unhealthy core nodes, use
to turn on termination protection. In such cases, Amazon EMR adds the unhealthy nodes
to a denylist, reducing job interruptions and failures.
If unhealthy node replacement is on, Amazon EMR notifies YARN and other applications on the cluster to stop scheduling tasks with these nodes, moves the data, and then terminates the nodes.
For more information, see graceful node replacement in the Amazon EMR Management Guide.
