------------------------------------

             Summary: Snapshot names should not be allowed to contain slash characters
                 Key: HDFS-5102
                 URL: https://issues.apache.org/jira/browse/HDFS-5102
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: snapshots
    Affects Versions: 2.1.0-beta
            Reporter: Aaron T. Myers


Snapshots of a snapshottable directory are allowed to have arbitrary names. Presently, if you create a snapshot with a snapshot name that begins with a "/" character, this will be allowed, but later attempts to access this snapshot will fail because of the way the {{Path}} class deals with consecutive "/" characters. I suggest we disallow "/" from appearing in snapshot names.

An example of this is in the first comment on this JIRA.
