Further instigation (and some assistance with jsanda) was able to determine that this is an environment issue not a code issue. My /etc/hosts file (on OS/X) did not have an entry mapping ip to localhost: 192.168.1.X localhost After adding this entry, the installation proceeded without fail. I have recreated the failing condition and then fix it using the /etc/hosts entry for ip --> localhost. Mike and John, can you better explain what happened, what is the right setup (and perhaps add something to the installer to help users get this set up correctly)? Perhaps improve the NoHostAvailableException to give some helpful text or a link to the docs at least And then work with Deon to document this? changing this to a doc bug. no code change. and QE has tested install many times.

More specifically, it looks like this happens if there is no DNS entry for the ip address. So you must provide the DNS either in DNS or in /etc/hosts. This is related to Bug 1010265 (probably even a dup) Moving into ER3 as didn't make it into ER2. Remove the blocker on beta and set it to GA, as it is a docs task and the implementation has been taken care of in Bug 1010265 Mass closure of bugs modified in 2013. All of these are in the currently-published docs. |
Users trying to install a fresh 4.8 / 4.9 fail with > NoHostAvailableException: All host(s) tried for query failed We need make that work (automatically) and document what needs to be done or how users can get going if the automatic setup fails
