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 -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
