@sankar rao

hdfs acl is implemented in HDFS version 2.4.0, which is included in HDP 2.1.2. If not found, you can add it from ambari

Ambari Dasboard>HDFS>Configuration>Advanced>Custom hdfs-site

Add property dfs.namenode.acls.enabled=true

Restart the services to take this effect

should i add Add property dfs.namenode.acls.enabled=true in download time of cluster or can i added any time?

the resoans for asking is after adding should we need to restart any services which will effect the correct jobs..?
