Bug #8828

Updated by Ward Vandewege almost 8 years ago

I noticed two small issues introduced after the changes in 8815 - I should have spotted them in review, sorry. Specifically, we had the diagnostics fail on c97qk with:

 Two issues here: 

 a) the 'which crunchrunner' lookup is apparently happening on the API server, not on the compute node: the compute node had crunchrunner installed, but the API server did not. I installed it there, and that fixed the problem. Clearly, the test should happen on the compute node. 

 b) when 'which crunchrunner' doesn't find the executable, we shouldn't try to append half a volume statement to the docker run command, that breaks the invocation (and thus fails the job).
