Re: [HTCondor-users] Fwd: Manually Setting ClusterID

[Ben Cotton <ben.cotton@xxxxxxxxxxxxxxxxxx>]

Francisco,

Good news! SCHEDD_CLUSTER_INITIAL_VALUE is the schedd setting you
want. From the manual:

An integer that specifies the initial cluster number value to use
within a job id when a job is first submitted. If the job cluster
number reaches the value set by SCHEDD_CLUSTER_MAXIMUM_VALUE and
wraps, it will be re-set to the value given by this variable. The
default value is 1.

It might be a good idea, if it's possible, to modify your external
services to use GlobalJobId to identify jobs instead of just the
straight job id. I have a patch submitted (poke, poke, Todd) to add
the following to the ClassAd reference:

A globally-unique job identifier. Contains the queue name, JobId, and
schedd start time (in seconds since Jan 1, 1970) joined by #. For
example, submit.example.com#152.3#1358363336

The inclusion of the schedd start time helps prevent issues like
you're encountering (plus eventually the odometer will reset on your
cluster ID anyway).


Thanks,
BC
