             Summary: Error in Windows agent's Flags::runtime_dir CLI
                 Key: MESOS-6677
                 URL: https://issues.apache.org/jira/browse/MESOS-6677
             Project: Mesos
          Issue Type: Bug
          Components: cli
    Affects Versions: 1.2.0
         Environment: Windows 10
Commit b7937a68367088f3c1f7c334307422c71737b1d7

            Reporter: Andrew Schwartzmeyer
            Assignee: Andrew Schwartzmeyer
            Priority: Minor


Error occurs at runtime due to runtime_dir initialization code in the CLI.
Code attempts to get the current user's name (which throws an error on Windows):


{{F1202 14:43:16.214303  9816 flags.cpp:215] CHECK_SOME(user): The request is not supported.}}

{{*** Check failure stack trace: ***}}


While https://reviews.apache.org/r/53706/ implements {{os::user}}, the default is still incorrect for Windows as it switches on the Linux user "root", and would cause the hard-coded Linux default to be used in the edge case of a user named "root" on Windows.

The fix is to use a proper Windows location for persistent data.
