I assume this is basically the same as Bug 54786 ('Make exec hosts as submit hosts too'), just concerning tools-webgrid-tomcat. Trying to submit a job to SGE results in this error message:
Unable to initialize environment because of error: denied: host "tools-webgrid-tomcat.eqiad.wmflabs" is neither submit nor admin host
I do not usually over-estimate the severity of bugs, but this one would be really good to have fixed before the Toolserver shuts down. This is the last thing I need before I can have one of my tools (which replaces the Catgraph tool on the Toolserver) run on Tomcat - instead of the kludgy alternative solution I have now.
