[jira] [Commented] (HADOOP-11640) add user defined delimiter
support to Configuration
[ https://issues.apache.org/jira/browse/HADOOP-11640?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16436104#comment-16436104 ]
Jim Brennan commented on HADOOP-11640:
--------------------------------------
MAPREDUCE-7069 provides a solution for this specifically for the mapreduce environment properties ({{mapreduce.map.env}}, {{mapreduce.reduce.env}}, etc...) by providing the ability to specify variables individually. e.g., {{mapreduce.map.env.VARNAME=value}}.

> As mentioned by org.apache.hadoop.conf.Configuration.getStrings ("Get the comma delimited values of the name property as an array of Strings"), only comma separated strings can be used. It would be much better if user defined separators are supported.
