Common errors in Amazon EMR

Sometimes, clusters fail or are slow to process data. The following sections list some common cluster issues With suggestions on how to fix them.

Find a missing cluster

If your cluster is missing from the console list or ListClusters API, check the following:

  • Confirm that the cluster age from time of completion is less than two months. Amazon EMR preserves metadata information for completed clusters for two months at no charge. You can't delete completed clusters from the console — instead, Amazon EMR purges completed clusters automatically after two months.

  • Confirm that you have role permissions to view the cluster.

  • Confirm that you are viewing the same Amazon Web Services Region where the cluster resides.
