Review request for Ambari, Laszlo Puskas, Robert Nettleton, Sandor Magyari,
Sumit Mohanty, and Sebastian Toader.
Bugs: AMBARI-17219
https://issues.apache.org/jira/browse/AMBARI-17219
Repository: ambari
Description
-------
When a host is removed, it is necessary to have all the components stopped and
removed, before the host itself can be deleted.
If a host component is not stopped, it is not allowed to be removed, so the
host itself cannot be removed. However if re-adding the host is tried, even if
it is still in the cluster, a row is inserted to topology_host_info table.
Multiple lines of the same host in that table is incorrect, so topology
validation fails.
Expected behaviour: if host is still in the cluster, a duplicate should not be
able to be persisted in any of the related tables.
