Subject [jira] [Created] (MAPREDUCE-3825) Need generalized multi-token filesystem support
Date Mon, 06 Feb 2012 23:24:59 GMT
Need generalized multi-token filesystem support

                 Key: MAPREDUCE-3825
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3825
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: security
    Affects Versions: 0.23.1, 0.24.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp

This is the counterpart to HADOOP-7967.  The token cache currently tries to assume a filesystem's
token service key.  The assumption generally worked while there was a one to one mapping of
filesystem to token.  With the advent of multi-token filesystems like viewfs, the token cache
will try to use a service key (ie. for viewfs) that will never exist (because it really gets
the mounted fs tokens).
