Subject [jira] [Commented] (HADOOP-11640) add user defined delimiter support to Configuration
Date Tue, 03 Mar 2015 07:36:04 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11640?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14344681#comment-14344681

Haohui Mai commented on HADOOP-11640:
-------------------------------------

I agree with Colin that it makes more sense for an escaping mechanism instead of making it
configurable. Not only it is an incompatible change, {{Configuration}} is performance-critical
and I'm concerned about the performance penalty it introduces.

> 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.
