Disable manage.include.files for Yarn

Using Ambari Web, disnable automated host participation by setting manage.include.files properties to false in the YARN configuration.

When manage.include.files is disabled, Ambari does not manage the files that include and exclude hosts participating in cluster operations. Ambari will not updates these files based on the state of hosts as displayed in Ambari Web. Set the manage.include.files=false and remove the yarn.resourcemanager.nodes.include-path property from the YARN configuration to disable automated host file participation for the YARN service.

Using Ambari Web, browse to Services > YARN.
In the Advanced yarn-site configuration section, set the manage.include.files property to false.
In the Custom yarn-site configuration section, remove the yarn.resourcemanager.nodes.include-pathproperty.
Restart services, as prompted by Ambari.

When manage.include.files is disabled, Ambari does not manage the files that include and exclude hosts participating in cluster operations.
