Re: [Condor-users] Migrating 7.2->7.4 job submission woe


Check the configuration of ALLOW_NEGOTIATOR and ALLOW_NEGOTIATOR_SCHEDD in the configuration of the submit machine.

Let me know if it still doesn't make sense.

I'm testing out v7.4.2 of Condor and have run into a job submission problem. Firstly, I should say that the pool is an upgraded 7.2.5 pool, with the same condor_config file but with HOSTALLOW/HOSTDENY entries changed to ALLOW/DENY, as recommended in the release notes for 7.4.0. Submitting a simple test job fails to run, even though "condor_q -better" shows that there are available resources. A look at the NegotiatorLog has the relevant snippet:

04/13 16:33:49 Negotiating with xxxx@xxxxxxxxxxxxx at <>
04/13 16:33:49 0 seconds so far
04/13 16:33:49 condor_read() failed: recv() returned -1, errno = 104 Connection reset by peer, reading 5 bytes from schedd xxxx@xxxxxxxxxxxxxx
04/13 16:33:49 IO: Failed to read packet header
04/13 16:33:49     Failed to get reply from schedd

A look at the corresponding entry in the submitter's SchedLog has:

04/13 16:33:36 (pid:19045) Sent ad to central manager for xxxx@xxxxxxxxxxxxx
04/13 16:33:36 (pid:19045) Sent ad to 1 collectors for xxxx@xxxxxxxxxxxxx
04/13 16:33:49 (pid:19045) Unknown negotiator ( Aborting negotiation.

As can be surmised from the above, the submit host has IP address and the central manager has It looks like the Schedd doesn't trust the Negotiator, right? By comparison, when I submit the same job from a machine still running 7.2.5 to the same central manager, then the job runs just fine. That is:

submit host (7.4.2) -> central manager (7.4.2): Fails
submit host (7.2.5) -> central manager (7.4.2): Succeeds

Is there some new/extra configuration that needs to be carried out on a submit host running 7.4 compared to that on 7.2?
