[jira] [Commented] (MESOS-3296) Failing ROOT_ tests on CentOS 7.1 - LinuxFilesystemIsolatorTest

["Greg Mann (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-3296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14705255#comment-14705255 ] 

Greg Mann commented on MESOS-3296:
----------------------------------

It looks like all of the LinuxFilesystemIsolator tests are failing on CentOS because they don't have access to {{sh}}; they attempt to run a command through the shell and {{execlp()}} gives {{errno = 2}}, file not found. I'm guessing this may be due to the simple fact that CentOS doesn't have a discrete {{/bin}} directory, but rather it's just a symlink to {{/usr/bin}}. This is in contrast to Ubuntu which has a separate {{/bin}}. I can't seem to find where we are mounting {{/bin}} in the isolator creation process, perhaps somebody with more intimate knowledge of this code ([~idownes], [~jieyu]?) could shed some light on it.
