```
    Applies only when CustomAmiID is used. Specifies which updates from the Amazon Linux AMI package repositories to apply automatically when the instance boots using the AMI. If omitted, the default is SECURITY, which indicates that only security updates are applied. If NONE is specified, no updates are applied, and all updates must be applied manually.
    
    If the service returns an enum value that is not available in the current SDK version, repoUpgradeOnBoot will return RepoUpgradeOnBoot.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from repoUpgradeOnBootAsString().
    
    Returns:

  - kerberosAttributes
```
public final KerberosAttributes 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.

  - stepConcurrencyLevel
```
public final Integer stepConcurrencyLevel()
```
    Specifies the number of steps that can be executed concurrently. The default value is 1. The maximum value is 256.

  - managedScalingPolicy
```
public final ManagedScalingPolicy managedScalingPolicy()
```
    The specified managed scaling policy for an Amazon EMR cluster.
    
    Returns:
    
    The specified managed scaling policy for an Amazon EMR cluster.
  - hasPlacementGroupConfigs
```
public final boolean hasPlacementGroupConfigs()
```
    For responses, this returns true if the service returned a value for the PlacementGroupConfigs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - placementGroupConfigs
```
public final List<PlacementGroupConfig> placementGroupConfigs()
```
    The specified placement group configuration for an Amazon EMR cluster.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasPlacementGroupConfigs() method.
    
    Returns:
    
    The specified placement group configuration for an Amazon EMR cluster.
  - autoTerminationPolicy
```
public final AutoTerminationPolicy autoTerminationPolicy()
```
    Returns the value of the AutoTerminationPolicy property for this object.
    
    Returns:
    
    The value of the AutoTerminationPolicy property for this object.
  - osReleaseLabel
```
public final String osReleaseLabel()
```
    Specifies a particular Amazon Linux release for all nodes in a cluster launch RunJobFlow request. If a release is not specified, Amazon EMR uses the latest validated Amazon Linux release for cluster launch.
    
    Returns:
    
    Specifies a particular Amazon Linux release for all nodes in a cluster launch RunJobFlow request. If a release is not specified, Amazon EMR uses the latest validated Amazon Linux release for cluster launch.
