There are many reasons why a cluster might fail or be slow in processing data. The following sections list the most common issues and suggestions for fixing them.
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. If the
VisibleToAllUsers property is set to false, other
users in the same IAM account will not be able to view a cluster.
You are viewing the correct region.
