Here is the description for the LB:
Address of the load balancer used if Oozie HA is enabled. Should be specified in host:port format.
Could we improve it to "FQHN:port" and ask technical writer to update it? Kerberos only treats FQHN well.
@zhuw.bigdata, I opened two internal Cloudera Jiras to make sure we specify that the fully-qualified domain name be used if Kerberos is enabled in the cluster. One Jira targeted the description in the HA wizard, the other Jira focused on the steps listed in our the documentation.
Thanks for bringing this up!
