[jira] [Commented] (MESOS-3293) Failing ROOT_ tests on CentOS 7.1 - LimitedCpuIsolatorTest

["Jian Qiu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-3293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14738278#comment-14738278 ] 

Jian Qiu commented on MESOS-3293:
---------------------------------

../../src/tests/containerizer/isolator_tests.cpp:731: Failure
Value of: usage.get().processes()
Actual: 2
Expected: 1U
Which is: 1
../../src/tests/containerizer/isolator_tests.cpp:732: Failure
Value of: usage.get().threads()
Actual: 2
Expected: 1U
Which is: 1

The reason is that the test case run 'sh -c "while true; do sleep 1; done;"' in the container which generates one additional child process
root 18581 0.0 0.0 4448 1496 pts/0 S+ 04:06 0:00 sh -c while true; do sleep 1; done;
root 18592 0.0 0.0 7200 652 pts/0 S+ 04:06 0:00 sleep 1

So my proposal is either change the test command to something like "exec sleep 60" or change the expect value to 2
