Subject [jira] [Commented] (MAPREDUCE-2864) Renaming of configuration property names in yarn
Date Wed, 31 Aug 2011 19:06:09 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2864?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13094799#comment-13094799
] 

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

This is a quick note that the patch does not apply to 0.23 branch because one of the lines
in yar-default.xml has a version number in it

{code}
<     <!--<value>~/Workspace/eclipse-workspace/yarn/yarn-mapreduce/yarn-mapreduce-app/target/yarn-mapreduce-app-0.24.0-SNAPSHOT.jar</value>-->
---
>     <!--<value>~/Workspace/eclipse-workspace/yarn/yarn-mapreduce/yarn-mapreduce-app/target/yarn-mapreduce-app-0.23.0-SNAPSHOT.jar</value>-->
{code}

I can make a separate patch for it if necessary after the reviews are in.

> 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.
