             Summary: Containerizer logging modularization
                 Key: MESOS-4086
                 URL: https://issues.apache.org/jira/browse/MESOS-4086
             Project: Mesos
          Issue Type: Epic
          Components: containerization, modules
            Reporter: Joseph Wu
            Assignee: Joseph Wu


Executors and tasks are configured (via the various containerizers) to write their output (stdout/stderr) to files ("stdout" and "stderr") on an agent's disk.

Unlike Master/Agent logs, executor/task logs are not attached to any formal logging system, like {{glog}}.  As such, there is significant scope for improvement.

By introducing a module for logging, we can provide a common/programmatic way to access and manage executor/task logs.  Modules could implement additional sinks for logs, such as:
* to the sandbox (the status quo),
* to syslog,
* to journald

This would also provide the hooks to deal with logging related problems, such as:
* the (current) lack of log rotation,
* searching through executor/task logs (i.e. via aggregation)
