Jie Yu commented on MESOS-2462:
-------------------------------
One solution is to force 'du' and 'perf' to use the argv version of the
subprocess and assume that they are under /usr/bin
I checked a few distributions (e.g. osx, ubuntu, centos, fedora), that's the
case for all of them.
> Add option for Subprocess to set a death signal for the forked child
> --------------------------------------------------------------------

> Key: MESOS-2462
> URL: https://issues.apache.org/jira/browse/MESOS-2462
> Project: Mesos
> Issue Type: Improvement
> Components: isolation
> Affects Versions: 0.21.1
> Reporter: Ian Downes
> Assignee: Jie Yu
> Priority: Minor
> Labels: twitter
>
> Currently, children forked by the slave, including those through Subprocess,
> will continue running if the slave exits. For some processes, including
> helper processes like the fetcher, du, or perf, we'd like them to be
> terminated when the slave exits.
> Add support to Subprocess to optionally set a DEATHSIG for the child, e.g.,
> setting SIGTERM would mean the child would get SIGTERM when the slave
> terminates.
> This can be done (*after forking*) with PR_SET_DEATHSIG. See "man prctl". It
> is preserved through an exec call.
