Returns a description of the MSK cluster whose Amazon Resource Name (ARN) is specified in the request. The following is a Python 3.6 example of how to use this operation. Before you run this Python script, replace the example cluster Amazon Resource Name (ARN) with the ARN of the cluster you want to describe. If you don't know the ARN of the cluster, you can use the ListClusters operation to list all the clusters and see their ARNs and full descriptions.

If you use the US West (N. California) Region, specify exactly two subnets. For other Regions where Amazon MSK is available, you can specify either two or three subnets. The subnets that you specify must be in distinct Availability Zones. When you create a cluster, Amazon MSK distributes the broker nodes evenly across the subnets that you specify.

Client subnets can't occupy the Availability Zone with ID use1-az3.
