Subject [jira] [Commented] (MAPREDUCE-2864) Renaming of configuration property names in yarn
Date Fri, 02 Sep 2011 15:20:09 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2864?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13096039#comment-13096039
] 

Robert Joseph Evans commented on MAPREDUCE-2864:
------------------------------------------------

I went through all of the findbugs warnings in YARN, and none of them have anything to do
with the changes I have made.  I am not sure why findbugs is complaining that these issues
are new.  Could someone please commit this sooner rather then later.  It has a big impact
on a number of files and I will have to keep upmerging the patch if it does not go in quickly.
 Also as it goes in please e-mail the dev list to indicate that the config values have changed
and give a reference to the script to update them.

> Now that YARN has been put in to trunk we should do something similar to MAPREDUCE-849.
 We should go back and look at all of the configurations that have been added in and rename
them as needed to be consistent and subdivided by component.
> # We should use all lowercase in the config names. e.g., we should use appsmanager instead
of appsManager etc.
> # history server config names should be prefixed with mapreduce instead of yarn.
