Our ops people use the "start-here.sh" scripts to bring services back up after failures. That's a great convenience: they don't have to remember which hosts are supposed to run the which service.
In sympathy with your hostname troubles: the inconsistent use of hostname determination causes those tservers started with start-all.sh and start-here.sh to have different hostnames (shortname and fqdn, respectively). This has something to do with how our DNS is set-up (or hardcoded) because I cannot reproduce the effect in my development environment. As a consequence of this, the quoting hell of ssh, the limitations of writing code in Bash, I'm avoiding The Scripts as much as possible. I am happy you are taking this on. -Eric On Thu, Jun 25, 2015 at 1:24 PM, Josh Elser <josh.el...@gmail.com> wrote: > I've been on a tear within our scripts in the last day.
