[STORM-733] ShellBolts that don't respond to heartbeats are not being killed
[STORM-734] When ShellBolt dies it calls System.exit, which doesn't always
shut the process down

>
> Key: STORM-733
> URL: https://issues.apache.org/jira/browse/STORM-733
> Project: Apache Storm
> Issue Type: Bug
> Affects Versions: 0.9.3
> Reporter: Re'em Bensimhon
> Assignee: Re'em Bensimhon
> Priority: Critical
>
> In cases where a multilang bolt is stuck (say, an infinite loop), the
> heartbeats are supposed to detect the issue and kill the supervisor process.
> In 0.9.3 this doesn't happen due to
> backtype.storm.utils.ShellProcess.getErrorsString() call in ShellBolt.die()
> This call, which in turn executes IOUtils.toString(processErrorStream) will
> block the thread until process exits. Heartbeat flow should not assume
> process had exited.
