> bin/storm.py emits the following crucial information that is lost because we
> don't flush the stdout before exec.
> {code}
> 2016-04-25T08:23:43.17141 Running: java -server -Dstorm.options=
> -Dstorm.home= -Xmx1024m -Dlogfile.name=nimbus.log

> {code}
> OS: CentOS release 6.5

> Python version: Python 2.7.2
> {code}
> For example, I using runit to start storm components like nimbus, ui, etc and
> the problem is applicable to all the components and in all the cases, I am
> not seeing logs that are emitted by bin/storm before {{os.execvp}} is called
> to actually launch the component.
> Please note that in cases where stdout and stderr is terminal, the stdout and
> stderr are always flushed and the bug is not applicable.
