Description

• https://cwiki.apache.org/confluence/display/HADOOP/Secure+DataNode
• https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SecureMode.html

When kerberos enabled and unprivileged port for datanode is used, pid file name is hadoop-hdfs-datanode.pid, not hadoop-hdfs-root-datanode.pid.

To determine which pid file is used when checking the status of DataNode, secure_dn_ports_are_in_use should be used instead of security_enabled.
