We shall obey the sort order as specified > in the script. > For example, the following script does not do the right thing if we turn off > secondary sort (which means, we will rely on POSort to sort): > {code} > A = load 'input' as (a0:int); > B = group A ALL; > C = foreach B { > D = order A by a0 desc; > generate D; > }; > dump C; > {code} > If we run it using the command line "java -Xmx512m > -Dpig.exec.nosecondarykey=true -jar pig.jar 1.pig". > The sort order for D is ascending. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
