> PerfTest.ROOT_SampleInit test fails.
> ------------------------------------
>
> Key: MESOS-2534
> URL: https://issues.apache.org/jira/browse/MESOS-2534
> Project: Mesos
> Issue Type: Bug
> Components: test
> Affects Versions: 0.22.0
> Reporter: Benjamin Mahler
> Assignee: Ian Downes
> Labels: twitter
>
> From MESOS-2300 as well, it looks like this test is not reliable:
> {code}
> [ RUN ] PerfTest.ROOT_SampleInit
> ../../src/tests/perf_tests.cpp:147: Failure
> Expected: (0u) < (statistics.get().cycles()), actual: 0 vs 0
> ../../src/tests/perf_tests.cpp:150: Failure
> Expected: (0.0) < (statistics.get().task_clock()),
> {code}
> It looks like this test samples PID 1, which is either {{init}} or
> {{systemd}}. Per a chat with [~idownes] this should probably sample something
> that is guaranteed to be consuming cycles.
