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

             Summary: Add tracking IDs to FS tokens to allow tracing FS operations back to
job
                 Key: HADOOP-9775
                 URL: https://issues.apache.org/jira/browse/HADOOP-9775
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
    Affects Versions: 2.1.0-beta
            Reporter: Sandy Ryza
            Assignee: Sandy Ryza


It would be helpful for auditing to allow tracing of file system operations to the higher-level
operations that encompass them (e.g. MR jobs).

Approaches to achieving this by logging delegation token sequence numbers at job start were
discussed on MAPREDUCE-5379, but rejected because delegation token identifiers are meant to
be opaque.

Per discussion between Tucu and Daryn, a better way to do this would be to include a tracking
ID with delegation tokens.  When requesting a delegation token, a job would be able to pass
its job ID along to be included with the token.
