Subject [jira] [Created] (YARN-279) Generalize RM token management
Date Thu, 20 Dec 2012 16:41:12 GMT
Daryn Sharp created YARN-279:
--------------------------------

             Summary: Generalize RM token management
                 Key: YARN-279
                 URL: https://issues.apache.org/jira/browse/YARN-279
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: resourcemanager
    Affects Versions: 0.23.5, 2.0.0-alpha, 3.0.0
            Reporter: Daryn Sharp


Token renewal/cancelation in the RM presents challenges to support arbitrary tokens.  The
RM's CLASSPATH is currently required to have token renewer classes and all associated classes
for the project's client.  The logistics of having installs on the RM of all hadoop projects
that submit jobs - just to support client connections to renew/cancel tokens - are untenable.
