Subject [jira] Commented: (HADOOP-3479) Implement configuration items useful for Hadoop resource manager (v1)
Date Fri, 13 Jun 2008 17:07:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12604931#action_12604931

Hemanth Yamijala commented on HADOOP-3479:

One of the problems I am facing in visualizing a consistent syntax and API is that the Hadoop
configuration is a single list of key-value pairs expressed in an XML format. So, the basic
Configuration API is a *String get(String property)*. With the resource manager changes, we
have to support groups of such key-value pairs, where each instance of such a group represents
related configuration for a single queue. In other words, a simple get(String property) no
longer works. You need to tell for which instance you have to get the property. Any ideas
on how to define a consistent API to represent both ?
