Subject [jira] Created: (MAPREDUCE-2293) Enhance MultipleOutputs to allow additional characters in the named output name
Date Tue, 01 Feb 2011 16:38:29 GMT
Enhance MultipleOutputs to allow additional characters in the named output name
-------------------------------------------------------------------------------

                 Key: MAPREDUCE-2293
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2293
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
    Affects Versions: 0.21.0
            Reporter: David Rosenstrauch
            Priority: Minor


It Currently you are only allowed to use alpha-numeric characters in a named output name in
the MultipleOutputs class.  This is a bit of an onerous restriction, as it would be extremely
convenient to be able to use non alpha-numerics in the name too.  (E.g., a '.' character would
be very helpful, so that you can use the named output name for holding a file name/extension.
 Perhaps '-' and a '_' characters as well.)

The restriction seems to be somewhat arbitrary - it appears to be only enforced in the checkTokenName
method.  (Though I don't know if there's any downstream impact by loosening this restriction.)

Would be extremely helpful/useful to have this fixed though!
