--------------------------------------------------------------------

Upgrading cluster from HDP2.2/Trafodion1.3 to HDP2.3/Trafodion2.1 took a couple steps, since Ambari knows nothing about the Trafodion1.3.

1. Installed HDP2.3 stack
2. stopped Trafodion (sqstop)
3. Upgrade HDP - HBase failed to start because of hbase.coprocessor.region.classes
3a. Cleared that value, able to complete upgrade.
4. Add Service Trafodion (2.1)
4a. Get warning that hbase.coprocessor.region.classes does not have recommended value, so set it to recommended Trafodion value.

This worked, except that Trafodion upgrade required moving from JDK1.7 to 1.8, which was not flagged, and it needed not only to be changed in ambari setup, but also restart HBase to use it, then finally trafodion would start.

> Trafodion should be installable via Ambari. We can create an extension or management pack that would plug into ambari.
> The trafodion management commands (sqstart, sqstop, sq...) currently work across cluster via required ssh access. Eventually, we should get away from that, but in the mean time we can define a component/role on a single node to run these commands.
> Current installer also does not fit into the required architecture to run installation node-by-node. That needs to be re-factored, so that command-line install can share code with cluster-manager (e.g., ambari) install.
