In a managed Apache Hadoop environment—like an Amazon EMR cluster—when the storage capacity on your cluster fills up, there is no convenient solution to deal with it. This situation occurs because you set up Amazon Elastic Block Store (Amazon EBS) volumes and configure mount points when the cluster is launched, so it’s difficult to modify the storage capacity after the cluster is running. The feasible solutions usually involve adding more nodes to your cluster, backing up your data to a data lake, and then launching a new cluster with a higher storage capacity. Or, if the data that occupies the storage is expendable, removing the excess data is usually the way to go.
