Armand Grillet reassigned MESOS-7586:
-------------------------------------

    Assignee: Armand Grillet

> Make use of cout/cerr and glog consistent.
> ------------------------------------------

>                 Key: MESOS-7586
>                 URL: https://issues.apache.org/jira/browse/MESOS-7586
>             Project: Mesos
>          Issue Type: Bug
>            Reporter: Andrei Budnik
>            Assignee: Armand Grillet
>            Priority: Minor
>              Labels: debugging, log, newbie

> Some parts of mesos use glog before initialization of glog. This leads to 
> message like:
> “WARNING: Logging before InitGoogleLogging() is written to STDERR”
> Also, messages via glog before logging is initialized might not end up in a 
> logdir.
>  
> The solution might be:
> cout/cerr should be used before logging initialization.
> glog should be used after logging initialization.
>  
> Usually, main function has pattern like:
> 1. load = flags.load(argc, argv) // Load flags from command line.
> 2. Check if flags are correct, otherwise print error message to cerr and then 
> exit.
> 3. Check if user passed --help flag to print help message to cout and then 
> exit.
> 4. Parsing and setup of environment variables. If this fails, EXIT macro is 
> used to print error message via glog.
> 5. process::initialize()
> 6. logging::initialize()
> 7. ...
>  
> Steps 2 and 3 should use cout/cerr to eliminate any extra information 
> generated by glog like current time, date and log level.
> It is possible to move step 6 between steps 3 and 4 safely, because 
> logging::initialize() doesn’t depend on process::initialize().
> Some parts of mesos don’t call logging::initialize(). This should also be 
> fixed.
