Step 5 (Progress page after Create Checkpoint page)
* "Stop All Services"
make an API call to stop all services
* "Install Additional NameNode"
make an API call to install the additional NAMENODE component on the assigned host
* "Install JournalNodes"
make an API call to install the JOURNALNODE component on the assigned 3 hosts
* "Start JournalNodes"
make an API call to start all the JOURNALNODEs
* "Disable Secondary NameNode"
make an API call to change the state of the SECONDARY_NAMENODE to "MAINTENANCE" state
* "Reconfigure HDFS"
make an API call to install HDFS_CLIENT on the host(s) for the two NAMENODEs.  This pushes the config files (core-site and hdfs-site) to these hosts.  The backend takes care of pushing the config files even if these components are already installed.
