Details

    Description

      StorageID currently identifies both a Datanode and a storage attached to the Datanode. Once we start tracking multiple storages per datanode we would like to deprecate StorageID in favor of a DatanodeUuid for the datanode and a StorageUuid per storage.

      This Jira track replacing StorageID with DatanodeUuid wherever it is used to identify a Datanode.
