----------------------------------
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.
