Evans Ye commented on BIGTOP-1662:
----------------------------------

{quote}it can be handed down from there as a default to all the sub-classes 
(hdfs, yarn, mapred and httpfs).{quote}
Ok that's reasonable to me. These components won't adopt different realm at all.
{quote} All the realm-setting is already in place in cluster.yaml and should 
work:{quote}
Sorry I'm not that familiar with hiera, but now I get it, it should work. I've 
tested other components and the realm has been successfully propagated.
So, +1 on this patch, I'll commit this later.

> The changes from BIGTOP-1634 omit kerberos_realm and 
> hadoop_security_authentication variables from some classes so that they're 
> not correctly entered in the generated configuration files. Also, a hasty 
> "fix" to hadoop-env.sh causes all variables to remain unset always.
