-----------------------------------
Summary: Use Datanode UUID to identify Datanodes
Key: HDFS-5233
URL: https://issues.apache.org/jira/browse/HDFS-5233
Project: Hadoop HDFS
Issue Type: Sub-task
Components: datanode, namenode
Affects Versions: Heterogeneous Storage (HDFS-2832)
Reporter: Arpit Agarwal
Assignee: Arpit Agarwal
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.
