Subject [jira] [Commented] (MAPREDUCE-2863) Support web-services for RM & NM
Date Wed, 16 Nov 2011 00:45:52 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13150934#comment-13150934

Hitesh Shah commented on MAPREDUCE-2863:
----------------------------------------

We can probably skip the flexible list of attributes for the time being and just keep a fixed
output for now. As a first cut, as long as the output format allows for easy flexibility to
add new elements in later ( clients could continue to work as is if they skip the newly added
elements as the older format didn't have them ), we can make do with just having ids for the
time being. 

One suggestion though might be to provide the ids and possibly the urls ( tracking url in
case of apps for example ) if that is something worth considering. However just to be clear,
I am ok with just having ids for now and then adding new elements in later once we get a better
understanding of how folks would be using these apis.
