 ** ClusterArn **   <a name="EMR-Type-ClusterSummary-ClusterArn"></a>
The Amazon Resource Name of the cluster.  
Type: String  
Length Constraints: Minimum length of 20. Maximum length of 2048.  
Required: No

 ** Id **   <a name="EMR-Type-ClusterSummary-Id"></a>
The unique identifier for the cluster.

Length Constraints: Maximum length of 256.  
Required: No

 ** Name **   <a name="EMR-Type-ClusterSummary-Name"></a>
The name of the cluster.

 ** NormalizedInstanceHours **   <a name="EMR-Type-ClusterSummary-NormalizedInstanceHours"></a>
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.  
Type: Integer
