Subject Re: how to spawn a new process for a map/reduce task
Date Mon, 03 Mar 2008 04:02:19 GMT
We have a wrapper around ProcessBuilder for running shell commands called 
Shell (see o.a.h.u.Shell). The reason for this wrapper is better output and 
error handling for shell commands. Almost all the needs are 
addressed by this wrapper and it also provides a common and a consistent 
way to run shell commands whenever needed.
