Bug ID: 61102
Summary: Soften qdel behaviour from KILL
Product: Wikimedia Labs
Version: unspecified
Hardware: All
OS: All
Status: NEW

At the moment, qdel KILLs the job; this is a bit rude.
If jsub would call "qsub -notify", SGE would signal the job before KILLing it.
The signal is set by "execd_param"'s NOTIFY_KILL; default is SIGUSR1, I would
favour SIGTERM (or a SIGHUP -> SIGINT -> SIGTERM cascade) as I suppose more
programs will already have a suitable handler for that.
The queue parameter "notify" defines the interval between signals; given that
many jobs in Tools use database and other network connections, I would be
fairly generous here and propose 60 s (that means in the worst case of a SIGHUP
-> SIGINT -> SIGTERM -> SIGKILL cascade 180 s which I find acceptable; for
special cases, roots can always log into the exec node and kill at will).
