Review request for Ambari, Alejandro Fernandez, Jonathan Hurley, and Nate Cole.

Bugs: AMBARI-11810

Repository: ambari


All the rolling upgrade pre-checks may still need to run against a non-HDP stack. Use this
JIRA to make the check runnable based on properties (rollingupgrade.stack, rollingupgrade.version)
set in the /etc/ambari-server/conf/ Still default to HDP and if
the properties do not exist.

org.apache.ambari.server.checks.AbstractCheckDescriptor compares stack against hardcoded StackInfo
"HDP-2.2". the stack name and version info can be externalized into the /etc/ambari-server/conf/
in order to support non-HDP stacks.




Testing (updated)

Added new unit tests

Manual test
1. Verify that without the fix, no rolling upgrade prechecks ran, the Ambari web UI popped
open a dialog showing all the rolling upgrade precheck as failures.
2. with the fix, the prechecks ran, I got to see a warning dialog suggesting me to enable
HA for hive metastore as well as showing me hive/hadoop properties that RU will modify.
