Subject [jira] Commented: (HADOOP-6006) pipes does not allow jobconf values containing commas
Date Mon, 15 Jun 2009 04:26:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6006?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12719394#action_12719394

Christian Kunz commented on HADOOP-6006:
----------------------------------------

Okay, this makes the patch for the trunk out-dated.

Is there a chance for a hadoop-0.18.4 release? Then it would be nice if the submitted patch
could be added (it also ensures proper exit code of pipes jobs in case of failure, see HADOOP-6030).

> 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.
