Other issues

Do you not see the cluster you expect in the Cluster List page or in results returned from ListClusters API?

Check the following:

• The cluster age is less than two months. Amazon EMR preserves metadata information about completed clusters for your reference, at no charge, for two months. The console does not provide a way to delete completed clusters from the console; these are automatically removed for you after two months.

• You have permissions to view the cluster.

• You are viewing the correct region.
