Tiago Bember updated MAPREDUCE-5061:
------------------------------------
Assignee: (was: Tiago Bember)
> MultipleInputs can not manage path with glob characters like {a,b}
> ------------------------------------------------------------------
>
> Key: MAPREDUCE-5061
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5061
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Thierry Granger
> Priority: Minor
>
> Hello,
> The org.apache.hadoop.mapreduce.lib.input.MultipleInputs expects a
> configuration with :
> * the parameter mapreduce.input.multipleinputs.dir.mappers in the format
> <path 1>,<mapper class 1>;<path 2>,<mapper class 2>
> * the parameter mapreduce.input.multipleinputs.dir.formats in the format
> <path 1>,<input format class 1>;<path 2>,<input format class 2>
> The usage of the comma as separator unable the use of the glob characters
> {a,b} in the path (like : hdfs://localhost/user/foo/data201{2,3} ).
> I suggest to change the separator to another non-problematic one (maybe =).
> I patched the MultipleInputs code locally and found an other related issue :
> when the path are created, the string representing the path is not unescape
> (like it's done in the
> org.apache.hadoop.mapreduce.lib.input.FileInputFormat.getInputPaths method)
> which makes an invalid path in case of glob characters {a\,b}
> Thank you
