[jira] [Updated] (CRUNCH-120) The in-memory implementation does not
support secondary sorts
[ https://issues.apache.org/jira/browse/CRUNCH-120?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Josh Wills updated CRUNCH-120:
------------------------------
Attachment: CRUNCH-120.patch
First pass at this: refactors the key-value aggregation into a Shuffler abstraction that can be swapped out to support the secondary sorts when the GroupingOptions indicate that it's needed.
