We have just published Cascading 2.7.1, a minor maintenance release.
This release resolves the following issues:
- Fixed issue where c.p.GroupBy or c.p.CoGroup would fail if attempting to group or join incoming Fields.UNKNOWN tuple streams using relative positions in the grouping fields selectors.
- Fixed issue where c.u.ShutdownUtil could log a NPE if a hook is removed during JVM shutdown.
