Subject HA without Kerberos?
Date Thu, 22 Oct 2015 19:42:51 GMT
I was setting up HA NN w/o Kerberos and got pretty far but the
JournalNode's are complaining. It seems they require kerberos: there is no
setting to use  "simple" authentication and they do not respect the
hdfs-site.xml setting .

Is there any solution to this?

Otherwise:  why has  fault tolerance been conflated with security?  We can
certainly imagine a cluster requiring fault tolerance that has been air
gapped - and thus kerberos would not be required.
