Description

The document here mentioned five properties that need to be updated when the CGroups with Yarn feature is enabled via Ambari web UI. http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/NodeManagerCgroups.html

Right now, however, only one is auto-changed – "yarn.nodemanager.container-executor.class".

This is due to a mix of yarn-site.xml metainfo change and the properties name used in the stack_advisor.py
