Dhanya Balasundaran created AMBARI-21692:

             Summary: dfs.include file is created on all datanode hosts when 
Ambari manages include/exclude files
                 Key: AMBARI-21692
                 URL: https://issues.apache.org/jira/browse/AMBARI-21692
             Project: Ambari
          Issue Type: Bug
          Components: ambari-admin
    Affects Versions: 2.5.2
            Reporter: Dhanya Balasundaran
             Fix For: 2.5.2

- deploy cluster with default configs
- Update manage.include.files to true in hdfs-site.xml
- Add property dfs.hosts=/etc/hadoop/conf/dfs.include in cstm-hdfs-site.xml
- Create /etc/hadoop/conf/dfs.include on Namenode host
- Restart all required services
- dfs.include gets created on all datanode hosts. 

Tried the same with Yarn, yarn.include will be present only on Resourcemanager 
node and doesnt get created on any other nodes(eg: one with nodemanager)

Ideally dfs.include should not be created on all datanode hosts
