Sprint: Mesosphere Sprint 26
> UserCgroupIsolatorTest.ROOT_CGROUPS_UserCgroup fails on CentOS 6.6
> ------------------------------------------------------------------
>
> Key: MESOS-4035
> URL: https://issues.apache.org/jira/browse/MESOS-4035
> Project: Mesos
> Issue Type: Bug
> Environment: CentOS6.6
> Reporter: Gilbert Song
> Assignee: Jan Schlicht

> `ROOT_CGROUPS_UserCgroup` on CentOS6.6 with 0.26rc3. The environment setup on
> CentOS6.6 is based on latest update of /docs/getting-started.md. Either using
> devtoolset-2 or devtoolset-3 returns the same failure.
> If running `sudo ./bin/mesos-tests.sh
> --gtest_filter="*ROOT_CGROUPS_UserCgroup*"`, it would return failures as
> following log:
> {noformat}
> [==========] Running 3 tests from 3 test cases.
> [----------] Global test environment set-up.
> [----------] 1 test from UserCgroupIsolatorTest/0, where TypeParam =
> mesos::internal::slave::CgroupsMemIsolatorProcess

> -------------------------------------------------------------
> We cannot run any cgroups tests that require
> a hierarchy with subsystem 'perf_event'
