> Some parts of mesos use glog before initialization of glog, hence messages via glog might
not end up in a logdir:
> bq. WARNING: Logging before InitGoogleLogging() is written to STDERR
> The solution might be:
> {{cout/cerr}} should be used before logging initialization.
> {{glog}} should be used after logging initialization.
>  
> Usually, main function has initialization pattern like:
> # load = flags.load(argc, argv) // Load flags from command line.
> # Check if flags are correct, otherwise print error message to cerr and then exit.
> # Check if user passed --help flag to print help message to cout and then exit.
> # Parsing and setup of environment variables. If this fails, EXIT macro is used to print
error message via glog.
> # process::initialize()
> # logging::initialize()
>  
> Steps 2 and 3 should use {{cout/cerr}} to eliminate any extra information generated by
glog like current time, date and log level.
> It would be preferable to move step 6 between steps 3 and 4 safely, because {{logging::initialize()}}
doesn’t depend on {{process::initialize()}}.
> In addition, initialization of glog should be added, where it's necessary.
