> Key: MAPREDUCE-385
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-385
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Christian Kunz
> Assignee: Christian Kunz
> Attachments: patch.HADOOP-6006, patch.HADOOP-6006.0.18
>
>
> Currently hadoop pipes does not allow a
> -jobconf <key>=<value>,<key>=<value>...
> commandline parameter with one or more commas in one of the values of the
> key-value pairs.
> One use case is key=mapred.join.expr, where the value is required to have
> commas.
> And it is not always convenient to add this to a configuration file.
> Submitter.java could easily be changed to check for backslash in front of a
> comma before using it as a delimiter.
