> {{Process#waitFor()}} will block until the process finishes. There are situations where this will wait indefinitely. A similar case was in SshActionExecutor, fixed in OOZIE-3354.
> Let's check the code for other usages, and fix it.
> Maybe we should check if we can use somehow the Process#waitFor(long timeout, TimeUnit timeUnit) instead of it. The tricky part is that this method is available only in Java 8.
