We've built parallel sorting in TEZ-3837. It does sampling as output is generated and figure out a range partitioner for shuffle edge. Each reducer output a sorted span. This is mainly for external consumption since output files need to be read in certain order. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
