Description

Ambari marks all nodes with warnings including component failure which should have been shown as red failure.

This was caused by a failure to bootstrap the Registry Schema (AMBARI-21492), but Ambari showed only warnings against all cluster hosts, while each host had a blank warning against random components where it had aborted but there was nothing wrong with those components so no error outputs.

The failure during Registry Startup bootstrap script should have been shown as red failure not yellow warning as the only way I could find the root cause was to go through the nodes one by one, which luckily this is a small 9 node cluster a not a 50 - 100+ cluster as I might not have found it otherwise.

Post cluster install the Ops screen does show the red failure correctly, this appears to only be a bug with the cluster installer.
