yarn-site.xml misplaced entries?

yarn-site.xml misplaced entries?

Contributor
Hello,

I was trying to change the memory configuration settings (yarn-site.xml and mapred-site.xml) when I realized that mapreduce entries were manually placed in yarn-site.xml.

As far as I know these entries are misplaced, but it seems that YARN takes them anyway, because they are shown at the resource manager conf (resource_manager:8088/conf).

I say this because the resource manager configuration takes several properties from many of the configuration files, such as mapred-site / default, core-site / default.

I have not found official documentation about to place mapreduce properties within the YARN configuration file.

I think the properties should be placed according to their correct place beyond what the YARN configuration is taking.

Have you been through a situation similar to this one?
What do you think?

Thanks!
