Review request for Ambari, Alejandro Fernandez, Jonathan Hurley, Sid Wagle, and
Tom Beerbower.
Bugs: AMBARI-11728
https://issues.apache.org/jira/browse/AMBARI-11728
Repository: ambari
Description
-------
I've upgraded from Ambari 1.7 to 2.0 on my own cluster and I'm seeing the same
problem
Under ‘stacks and versions’, versions gives no information.
After going through a number of troubleshooting steps, such as refreshing
browser cache, restarting services, datanodes, rebooting etc, I think we can
come to the conclusion that this is a bug.
The upgrade document mentions this, however the advised actions don’t work.
---
We decided to make requirements for initial bootstrap more loose:
- at least one component should be upgraded on each non-client host
- any client-only/unhealthy host is skipped in checks
- at least one healthy/non-client host should be in a cluster during initial
bootstrap
So customer should be able to get to CURRENT version in most cases and solve
any existing issues after that
----
Server side should look good, still working on an agent side (not reporting
component version until agent restart).
Current agent changes should be safe (removal of a lot of dead component
status/version related code), but I realized that agent side refactor may be
too agressive for 2.1, so I'll probably create a separate jira and move
non-critical refactors out to 2.2. Removed code used to be useful before adding
v2 services (with python scripts) and now does nothing.

As of now, agent tests pass, did not check server tests yet.
Also, E2E live testing is still pending
