Description

• 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
