Re: [HTCondor-users] HTCondor Schedd and docker

Hi Andrew,

Excellent, means itâs not just that Iâve screwed up my container networking!

Yeah itâs a bit of a weird one.

Doing

condor_q -name 11e3ad4f744a

Looking at the CollectorLog it looks like the query that used the Name attribute of the Schedd didnât get passed through

2/18/15 12:08:12 (Sending 0 ads in response to query)
12/18/15 12:08:12 Query info: matched=0; skipped=1; query_time=0.000041; send_time=0.000049; type=Scheduler; requirements={( ( Name == "" ) )}; peer=<##ip##:27811>; projection={}

Iâm wondering if itâs something to do with how condor is internally forming the requirements to send to the collector, however I havenât spotted it in the debug output yet.

Cheers, Iain
