Typically each of these directories correspond to a volume with its own file system. All these directories are homogeneous and therefore identified as a single storage at the namenode. I propose, change to the current model where Datanode * is a * storage, to Datanode * is a collection * of strorages. -- This message was sent by Atlassian JIRA (v6.1#6144)
