[jira] [Updated] (MAPREDUCE-2293) Enhance MultipleOutputs to allow
additional characters in the named output name
[ https://issues.apache.org/jira/browse/MAPREDUCE-2293?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Harsh J updated MAPREDUCE-2293:
-------------------------------
Attachment: mapreduce.mo.removecheck.r5.diff
New patch that fixes deprecated constructors used for SequenceFile.Reader in the tests previously.
Any concern on the core changes though? This has been open for almost two years now, and still applies :)

> 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!
