[jira] [Commented] (MESOS-4038) SlaveRecoveryTests, UserCgroupIsolatorTests fail on CentOS 6.6

["Bernd Mathiske (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-4038?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15035685#comment-15035685 ] 

Bernd Mathiske commented on MESOS-4038:
---------------------------------------

It seems that the right "fix" is adding documentation about needing to have perf support, respectively what to expect on which kinds of VMs on how to set them up.

> All {{SlaveRecoveryTest.\*}} tests, {{MesosContainerizerSlaveRecoveryTest.\*}} tests, and {{UserCgroupIsolatorTest*}} tests fail on CentOS 6.6 with {{TypeParam = mesos::internal::slave::MesosContainerizer}}. They all fail with the same error:
> {code}
> [----------] 1 test from SlaveRecoveryTest/0, where TypeParam = mesos::internal::slave::MesosContainerizer
> [ RUN      ] SlaveRecoveryTest/0.ReconnectExecutor
> ../../src/tests/mesos.cpp:722: Failure
> cgroups::mount(hierarchy, subsystem): '/cgroup/perf_event' already exists in the file system
> -------------------------------------------------------------
> We cannot run any cgroups tests that require
> a hierarchy with subsystem 'perf_event'
> because we failed to find an existing hierarchy
> or create a new one (tried '/cgroup/perf_event').
> You can either remove all existing
> hierarchies, or disable this test case
> (i.e., --gtest_filter=-SlaveRecoveryTest/0.*).
> -------------------------------------------------------------
> ../../src/tests/mesos.cpp:776: Failure
> cgroups: '/cgroup/perf_event' is not a valid hierarchy
> [  FAILED  ] SlaveRecoveryTest/0.ReconnectExecutor, where TypeParam = mesos::internal::slave::MesosContainerizer (8 ms)
> [----------] 1 test from SlaveRecoveryTest/0 (9 ms total)
> [----------] Global test environment tear-down
> [==========] 1 test from 1 test case ran. (15 ms total)
