             Summary: Variable shadowing in 
HookManager::slavePreLaunchDockerHook
                 Key: MESOS-4693
                 URL: https://issues.apache.org/jira/browse/MESOS-4693
             Project: Mesos
          Issue Type: Bug
          Components: modules
    Affects Versions: 0.27.0
            Reporter: Kevin Devroede


It looks like the `name` parameter in `HookManager::slavePreLaunchDockerHook` 
is shadowed by the hook name defined in the `foreach (const string& name, 
availableHooks.keys())`.

Due to this, the hook receives its own name as a parameter instead of the 
container name. It seems to be the only method of HookManager affected by this 
shadowing.

See: https://github.com/apache/mesos/blob/0.27.0/src/hook/manager.cpp#L203

If that's really a bug, I'd be happy to submit a patch.
