> This is a regression introduced in 2.0.0.
> When doing SSH bootstrap of hosts via Install Wizard, the hosts are shown as
> "Preparing". When you click on the host, no information shows up. It gets
> stuck in this state until "Registering".
> In 1.7.0, "Preparing" state was very brief and immediately switched to
> "Installing".
> This is a BE issue.
> API returns "RUNNING" without any information when installing Ambari Agent on
> the hosts.
> This issue caused by absent of propagation fail of runing bootstrap.py
> (server side) to HostStatus which are pooled by UI.
> So If bootstrap.py has syntax errors or fails while imports python modules it
> cant create *.log and *.done files, so java code can wait infinitely until
> *.done file will be created.
> So solution of this issue is to propagate fatal errors of bootstrap.py to
> hostStatus info. In this case, setup of agents will fail and root cause of
> issue will be sent to UI
