-- SetTerminationProtection locks a cluster (job flow) so the EC2 instances
-- in the cluster cannot be terminated by user intervention, an API call,
-- or in the event of a job-flow error. The cluster still terminates upon
-- successful completion of the job flow. Calling
-- @SetTerminationProtection@ on a cluster is similar to calling the Amazon
-- EC2 @DisableAPITermination@ API on all EC2 instances in a cluster.
--
-- @SetTerminationProtection@ is used to prevent accidental termination of
-- a cluster and to ensure that in the event of an error, the instances
-- persist so that you can recover any data stored in their ephemeral
-- instance storage.
--
-- To terminate a cluster that has been locked by setting
-- @SetTerminationProtection@ to @true@, you must first unlock the job flow
-- by a subsequent call to @SetTerminationProtection@ in which you set the
-- value to @false@.
--
-- For more information,
-- see<https://docs.aws.amazon.com/emr/latest/ManagementGuide/UsingEMR_TerminationProtection.html Managing Cluster Termination>
-- in the /Amazon EMR Management Guide/.
