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.
emr_set_termination_protection(JobFlowIds, TerminationProtected)
[required] A list of strings that uniquely identify the clusters to protect. This identifier is returned by RunJobFlow and can also be obtained from DescribeJobFlows .
[required] A Boolean that indicates whether to protect the cluster and prevent the Amazon EC2 instances in the cluster from shutting down due to API calls, user intervention, or job-flow error.
svc$set_termination_protection( JobFlowIds = list( "string" ), TerminationProtected = TRUE|FALSE )
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
.
