Subject [jira] [Commented] (YARN-3051) [Storage abstraction] Create backing storage read interface for ATS readers
Date Sat, 20 Jun 2015 01:19:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-3051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14594243#comment-14594243
] 

Sangjin Lee commented on YARN-3051:
-----------------------------------

Hadoop's {{Configuration}} is actually (string, string). Typed values are passed on as strings
eventually to {{Configuration}}.

For example, the iterator for {{Configuration}}:

{code}
public Iterator<Map.Entry<String,String>> iterator();
{code}
