Mahadev konar commented on MAPREDUCE-2864:
------------------------------------------
Minor nit, just noticed this in the patch in yarn-default.xml:
{code}
- <name>nodemanager.aux.service.mapreduce.shuffle.class</name>
- <value>org.apache.hadoop.mapred.ShuffleHandler</value>
+ <name>mapreduce.job.jar</name>
+ <value/>
+<!--<value>~/Workspace/eclipse-workspace/yarn/yarn-mapreduce/yarn-mapreduce-app/target/yarn-mapreduce-app-0.24.0-SNAPSHOT.jar</value>-->
</property>
--->
{code}
I think we should remove this property name (mapreduce.job.jar) in
yarn-default.xml. This can be done when committing, no need to upload a new
patch.

> 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.
