Implementations§
source§impl Cluster
impl Cluster
sourcepub fn status(&self) -> Option<&ClusterStatus>
pub fn status(&self) -> Option<&ClusterStatus>
The current status details about the cluster.
sourcepub fn ec2_instance_attributes(&self) -> Option<&Ec2InstanceAttributes>
pub fn ec2_instance_attributes(&self) -> Option<&Ec2InstanceAttributes>
Provides information about the Amazon EC2 instances in a cluster grouped by category. For example, key name, subnet ID, IAM instance profile, and so on.
sourcepub fn instance_collection_type(&self) -> Option<&InstanceCollectionType>
pub fn instance_collection_type(&self) -> Option<&InstanceCollectionType>
The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions.
The instance group configuration of the cluster. A value of INSTANCE_GROUP indicates a uniform instance group configuration. A value of INSTANCE_FLEET indicates an instance fleets configuration.
sourcepub fn log_uri(&self) -> Option<&str>
pub fn log_uri(&self) -> Option<&str>
The path to the Amazon S3 location where logs for this cluster are stored.
sourcepub fn log_encryption_kms_key_id(&self) -> Option<&str>
pub fn log_encryption_kms_key_id(&self) -> Option<&str>
The KMS key used for encrypting log files. This attribute is only available with Amazon EMR 5.30.0 and later, excluding Amazon EMR 6.0.0.
sourcepub fn requested_ami_version(&self) -> Option<&str>
pub fn requested_ami_version(&self) -> Option<&str>
The AMI version requested for this cluster.
sourcepub fn running_ami_version(&self) -> Option<&str>
pub fn running_ami_version(&self) -> Option<&str>
The AMI version running on this cluster.
sourcepub fn release_label(&self) -> Option<&str>
pub fn release_label(&self) -> Option<&str>
The Amazon EMR release label, which determines the version of open-source application packages installed on the cluster. Release labels are in the form emr-x.x.x, where x.x.x is an Amazon EMR release version such as emr-5.14.0. For more information about Amazon EMR release versions and included application versions and features, see https://docs.aws.amazon.com/emr/latest/ReleaseGuide/. The release label applies only to Amazon EMR releases version 4.0 and later. Earlier versions use AmiVersion.
sourcepub fn auto_terminate(&self) -> bool
pub fn auto_terminate(&self) -> bool
Specifies whether the cluster should terminate after completing all steps.
sourcepub fn termination_protected(&self) -> bool
pub fn termination_protected(&self) -> bool
Indicates whether Amazon EMR will lock the cluster to prevent the Amazon EC2 instances from being terminated by an API call or user intervention, or in the event of a cluster error.
sourcepub fn visible_to_all_users(&self) -> bool
pub fn visible_to_all_users(&self) -> bool
Indicates whether the cluster is visible to IAM principals in the Amazon Web Services account associated with the cluster. When true, IAM principals in the Amazon Web Services account can perform Amazon EMR cluster actions on the cluster that their IAM policies allow. When false, only the IAM principal that created the cluster and the Amazon Web Services account root user can perform Amazon EMR actions, regardless of IAM permissions policies attached to other IAM principals.
The default value is true if a value is not provided when creating a cluster using the Amazon EMR API RunJobFlow command, the CLI create-cluster command, or the Amazon Web Services Management Console.
sourcepub fn applications(&self) -> Option<&[Application]>
pub fn applications(&self) -> Option<&[Application]>
The applications installed on this cluster.
A list of tags associated with a cluster.
sourcepub fn service_role(&self) -> Option<&str>
pub fn service_role(&self) -> Option<&str>
The IAM role that Amazon EMR assumes in order to access Amazon Web Services resources on your behalf.
sourcepub fn normalized_instance_hours(&self) -> Option<i32>
pub fn normalized_instance_hours(&self) -> Option<i32>
An approximation of the cost of the cluster, represented in m1.small/hours. This value is incremented one time for every hour an m1.small instance runs. Larger instances are weighted more, so an Amazon EC2 instance that is roughly four times more expensive would result in the normalized instance hours being incremented by four. This result is only an approximation and does not reflect the actual billing rate.
sourcepub fn master_public_dns_name(&self) -> Option<&str>
pub fn master_public_dns_name(&self) -> Option<&str>
The DNS name of the master node. If the cluster is on a private subnet, this is the private DNS name. On a public subnet, this is the public DNS name.
sourcepub fn configurations(&self) -> Option<&[Configuration]>
pub fn configurations(&self) -> Option<&[Configuration]>
Applies only to Amazon EMR releases 4.x and later. The list of configurations that are supplied to the Amazon EMR cluster.
sourcepub fn security_configuration(&self) -> Option<&str>
pub fn security_configuration(&self) -> Option<&str>
The name of the security configuration applied to the cluster.
sourcepub fn auto_scaling_role(&self) -> Option<&str>
pub fn auto_scaling_role(&self) -> Option<&str>
An IAM role for automatic scaling policies. The default role is EMR_AutoScaling_DefaultRole. The IAM role provides permissions that the automatic scaling feature requires to launch and terminate Amazon EC2 instances in an instance group.
sourcepub fn scale_down_behavior(&self) -> Option<&ScaleDownBehavior>
pub fn scale_down_behavior(&self) -> Option<&ScaleDownBehavior>
The way that individual Amazon EC2 instances terminate when an automatic scale-in activity occurs or an instance group is resized. TERMINATE_AT_INSTANCE_HOUR indicates that Amazon EMR terminates nodes at the instance-hour boundary, regardless of when the request to terminate the instance was submitted. This option is only available with Amazon EMR 5.1.0 and later and is the default for clusters created using that version. TERMINATE_AT_TASK_COMPLETION indicates that Amazon EMR adds nodes to a deny list and drains tasks from nodes before terminating the Amazon EC2 instances, regardless of the instance-hour boundary. With either behavior, Amazon EMR removes the least active nodes first and blocks instance termination if it could lead to HDFS corruption. TERMINATE_AT_TASK_COMPLETION is available only in Amazon EMR releases 4.1.0 and later, and is the default for versions of Amazon EMR earlier than 5.1.0.
sourcepub fn custom_ami_id(&self) -> Option<&str>
pub fn custom_ami_id(&self) -> Option<&str>
Available only in Amazon EMR releases 5.7.0 and later. The ID of a custom Amazon EBS-backed Linux AMI if the cluster uses a custom AMI.
sourcepub fn ebs_root_volume_size(&self) -> Option<i32>
pub fn ebs_root_volume_size(&self) -> Option<i32>
The size, in GiB, of the Amazon EBS root device volume of the Linux AMI that is used for each Amazon EC2 instance. Available in Amazon EMR releases 4.x and later.
sourcepub fn repo_upgrade_on_boot(&self) -> Option<&RepoUpgradeOnBoot>
pub fn repo_upgrade_on_boot(&self) -> Option<&RepoUpgradeOnBoot>
Applies only when CustomAmiID is used. Specifies the type of updates that the Amazon Linux AMI package repositories apply when an instance boots using the AMI.
sourcepub fn kerberos_attributes(&self) -> Option<&KerberosAttributes>
pub fn kerberos_attributes(&self) -> Option<&KerberosAttributes>
Attributes for Kerberos configuration when Kerberos authentication is enabled using a security configuration. For more information see Use Kerberos Authentication in the Amazon EMR Management Guide.
sourcepub fn cluster_arn(&self) -> Option<&str>
pub fn cluster_arn(&self) -> Option<&str>
The Amazon Resource Name of the cluster.
sourcepub fn outpost_arn(&self) -> Option<&str>
pub fn outpost_arn(&self) -> Option<&str>
The Amazon Resource Name (ARN) of the Outpost where the cluster is launched.
sourcepub fn step_concurrency_level(&self) -> Option<i32>
pub fn step_concurrency_level(&self) -> Option<i32>
Specifies the number of steps that can be executed concurrently.
sourcepub fn placement_groups(&self) -> Option<&[PlacementGroupConfig]>
pub fn placement_groups(&self) -> Option<&[PlacementGroupConfig]>
Placement group configured for an Amazon EMR cluster.
sourcepub fn os_release_label(&self) -> Option<&str>
pub fn os_release_label(&self) -> Option<&str>
The Amazon Linux release specified in a cluster launch RunJobFlow request. If no Amazon Linux release was specified, the default Amazon Linux release is shown in the response.
