Review request for Ambari, Nate Cole and Tom Beerbower.
Bugs: AMBARI-9697
https://issues.apache.org/jira/browse/AMBARI-9697
Repository: ambari
Description
-------
After enabling Kerberos, the WebHCat Server Status alert is always CRITICAL.
This is caused by two problems:
1) The lack of any kinit and curl combination when the cluster is kerberized
2) Assuming that cluster-env/security_enabled means SSL (which is does not!)
Consulted with the Kerberos folks that cluster-env/security_enabled is used to
indicate kerberization.
It appears that WebHCat doesn't have an SSL mode; So going back to the 1.7.0
alert with a hard-coded http:// scheme for now.

Testing
-------
Tested in a kerberized cluster to ensure that the changed code fixed the
CRITICAL alert. Took the service down to verify that the alert triggered
correctly.
Tested the alert in a regular cluster to ensure the non-kerberized path worked
as it has in the past.
Thanks,
Jonathan Hurley
