Review request for Ambari, Dmitro Lisnichenko, Jonathan Hurley, Sumit Mohanty, and Sid Wagle.

Bugs: AMBARI-10170

Repository: ambari


The older upgrade catalogs cannot use any of Entity models that are related to the hosts table
because the host_name is no longer present (instead the host_id).
For this reason, I changed the UpgradeCatalogs to use raw SQL.

Diffs (updated)

Created VMs with each of the following Ambari versions and tested these upgrade paths.
                           2.0.0 -> 2.1.0 (has known issues due to XML properties)
                  1.7.0 -> 2.0.0 -> 2.1.0 (has known issues due to the stacks table,
this removed Nagios service, which was tested in UpgradeCatalog200)
         1.6.1 -> 1.7.0 -> 2.0.0 -> 2.1.0 (has known issues due to the stacks table,
this updated the host_role_command table, which was tested in UpgradeCatalog170)
1.6.0 -> 1.6.1 -> 1.7.0 -> 2.0.0 -> 2.1.0

To get these work, I had to comment out certain functions that are known to fail today.

I ran local unit tests on ambari-server/src/test/java/org/apache/ambari/server/upgrade and
they passed.
