Subject [jira] [Created] (MAPREDUCE-3850) Avoid redundant calls for tokens in TokenCache
Date Fri, 10 Feb 2012 19:13:01 GMT
Avoid redundant calls for tokens in TokenCache
----------------------------------------------

                 Key: MAPREDUCE-3850
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3850
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: security
    Affects Versions: 0.23.1, 0.24.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


The {{TokenCache}} will repeatedly call the same filesystem for tokens.  This is inefficient
and can easily be changed to only call each filesystem once.
