> Hi all,
>  I have a Pig script where I set the parallelism using the following set 
> construct: "set default_parallel 100" . I modified the "MRPrinter.java" to 
> printout the parallelism
> {code}
> ...
> public void visitMROp(MapReduceOper mr)
> mStream.println("MapReduce node " + mr.getOperatorKey().toString() + " 
> Parallelism " + mr.getRequestedParallelism());
> ...
> {code}
> When I run an explain on the script, I see that the last job which does the 
> actual sort, runs as a single reducer job. This can be corrected, by adding 
> the PARALLEL keyword in front of the ORDER BY.
> Attaching the script and the explain output
> Viraj
