Sandbox 2.5 HDP 2.5 Ambari: 126.96.36.199
This morning we opened up the add service menu to see what was available. Then closed the browser (with the service window open - a service may have been selected but never hit next to actually start the installation). Now the add service menu is gone (See image below) and a status is posted across the top stating that "Add Service Wizard in Progress". We did not try to install (see image below).
Sorry, I should have said that. I did try an $ambari-server restart and no change. That was actually the first thing I did. I also looked in the server logs and didn't see anything interesting there, but wasn't 100% what to look for either. (Nothing significant under ERROR)
Ok, I was able resolve the problem this morning.
When I was seeing the problem in Ambari I was logged in as 'admin' user. It turns out that there was another user account which opened the 'add service' dialog (but had not begun any installation) and closed the browser window without exiting out of the dialog. By logging into that second account and closing the dialog I was able to interact with the cluster normally again.
It would've been nice if the system automatically cancelled the 'add service' dialog when the second users session had expired, or at least listed which user had initiated the action. As no installation had begun it just sat there waiting for user input for days, while also locking all other users out from making changes.
It would be nice if there was some sort of way to figure out which user is logged into ambari and had that wizard open. Do you know of any way to find out which user was logged?
