Disabling namenode HA

Hi all,

I’m getting a lot of trouble with the namenode HA mode I just enabled in my test cluster, and I would like to disable it.

Is there an automated way to do it?
The only doc I found about this is this webpage : http://docs.hortonworks.com/HDPDocuments/HDP1/HDP-1.3.3/bk_using_Ambari_book/content/install-ha-undoing_2x.html
Is it still up to date?

Thank you in advance.

Regards,
Orlando
