[jira] [Commented] (HADOOP-10308) Remove from core-default.xml unsupported 'classic' and add 'yarn-tez' as value for mapreduce.framework.name property

["Harsh J (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-10308?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13887410#comment-13887410 ] 

Harsh J commented on HADOOP-10308:
----------------------------------

We can remove 'classic' as it brings no value today, agreed.

Last I checked, we do not ship Tez as part of Apache Hadoop, so why add an option that needs to be in Tez's docs instead, one that will also need Tez to be fully present in order to work, if one makes the switch to it?

We should instead alter the description to make it sound more generic instead, that the values are not limited to yarn and local, and can instead be set to IDs specified by other MR or MR-like runtimes.

> 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.
