Configuring ACLs on HDFS

You must configure dfs.namenode.acls.enabled in hdfs-site.xml to enable ACLs on HDFS.

ACLs are disabled by default. When ACLs are disabled, the NameNode rejects all attempts to set an ACL.
Set dfs.namenode.acls.enabled = true in hdfs-site.xml.
<property>
  <name>dfs.namenode.acls.enabled</name>
