[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 ]
David Rosenstrauch updated MAPREDUCE-2293:
------------------------------------------
Description:
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!
