You must specify the cluster ID and the instance fleet ID. Use the list-instance-fleets command to retrieve instance fleet IDs. aws emr modify-instance-fleet --cluster-id 'j-12ABCDEFGHI34JK' / --instance-fleet InstanceFleetId='if-2ABC4DEFGHIJ4',TargetOnDemandCapacity=1,TargetSpotCapacity=1 Add a Task Instance Fleet to a Cluster If a cluster has only master and core instance fleets, you can use the add-instance-fleet command to add a task instance fleet. You can only use this to add task instance fleets. aws emr add-instance-fleet --cluster-id 'j-12ABCDEFGHI34JK' --instance-fleet InstanceFleetType=TASK,TargetSpotCapacity=1,/ LaunchSpecifications={SpotSpecification='{TimeoutDurationMinutes=20,TimeoutAction=TERMINATE_CLUSTER}'}, InstanceTypeConfigs=['{InstanceType=m5.xlarge,BidPrice=0.5}'] Configure Uniform Instance Groups With the instance groups configuration, each node type (master, core, or task) consists of the same instance type and the same purchasing option for instances: On-Demand or Spot. You specify these settings when you create an instance group. They can't be changed later. You can, however, add instances of the same type and purchasing option to core and task instance groups. You can also remove instances. To add different instance types after a cluster is created, you can add additional task instance groups. You can choose different instance types and purchasing options for each instance group. For more information, see Scaling Cluster Resources (p. 328) . This section covers creating a cluster with uniform instance groups. For more information about modifying an existing instance group by adding or removing instances manually or with automatic scaling, see Manage Clusters (p. 273) . Use the Console to Configure Uniform Instance Groups The following procedure covers Advanced options when you create a cluster. Using Quick options also creates a cluster with the instance groups configuration. For more information about using Quick Options , see the Getting Started tutorial. To create a cluster with uniform instance groups using the console 1. Open the Amazon EMR console at . 129

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
