-----------------------------------
Summary: Make StorageID a UUID
Key: HDFS-5115
URL: https://issues.apache.org/jira/browse/HDFS-5115
Project: Hadoop HDFS
Issue Type: Sub-task
Components: datanode
Affects Versions: 3.0.0
Reporter: Arpit Agarwal
Assignee: Arpit Agarwal
The Storage ID is currently generated from the DataNode's IP+Port+Random
components. This scheme will not work when we have separate Storage IDs for
each storage directory as there is a possibility of conflicts when an
unreliable storage is intermittently offline.
Converting it to a UUID makes collisions very unlikely.
