Tsuyoshi OZAWA commented on HADOOP-10308:
-----------------------------------------

[~qwertymaniac], agreed, but concrete values like yarn/local/yarn-tez can help 
users to setup.

My proposal is as follows:
{code} 
The runtime framework for executing MapReduce jobs.
Apache Hadoop supports local, yarn by default, but other framework name can be 
specified like yarn-tez.
For more detail, please see documents of a framework you'd like to execute 
MapReduce jobs on.
Note that classic is no more supported. 
{code}

[~e...@apache.org], could you review my proposal?

> Remove from core-default.xml unsupported 'classic' and add 'yarn-tez' as 
> value for mapreduce.framework.name property

> Classic mr-v1 is no more supported in trunk.
> On the other hand, we will soon have yarn-tez implementation of mapreduce 
> (tez layer allowing to have a single AM for all map-reduce jobs).
> core-default.xml must reflect this.
