Review request for Ambari, Dmitro Lisnichenko, Jonathan Hurley, Nate Cole, and
Srimanth Gunturi.
Bugs: AMBARI-12488
https://issues.apache.org/jira/browse/AMBARI-12488
Repository: ambari
Description
-------
Currently RU orchestration during upgrade/downgrade kills ZKFC on the active
NameNode to initiate a failover to standby. We should instead use the failover
command.
E.g.,
su hdfs -c 'hdfs haadmin -failover nn1 nn2'

Testing
-------
Tested this during an RU, in which the active NameNode did successfully
initiate an ha failover by calling the command.
Python unit tests passed.
