> PROBLEM: On HDP 1.3 installed by Ambari 1.6.1 after upgrade to Ambari 1.7, Ambari presenting
option to enable HA for the NameNode.  But HDP 1.3 is not supporting NN HA. 
> If customer, mislead by Ambari will try in enable HA, will get the following: 
> Ambari instructing: 
> Login to the NameNode host hdp2-2-1.lfedotov.com. 
> Put the NameNode in Safe Mode (read-only mode): 
> sudo su -l hdfs -c 'hdfs dfsadmin -safemode enter' 
> When customer logged in to namenode machine and try to execute demanded command he got
the following: 
> [root@HDP2-2-1 ~]# sudo su -l hdfs -c 'hdfs dfsadmin -safemode enter' 
> -bash: hdfs: command not found 
> [root@HDP2-2-1 ~]# 
> Because "hdfs" command is not exists in HDP 1.3.
