             Summary: Object reuse bug in o.a.c.lib.Distinct
                 Key: CRUNCH-191
                 URL: https://issues.apache.org/jira/browse/CRUNCH-191
             Project: Crunch
          Issue Type: Bug
            Reporter: Gabriel Reid


A DoFn in the o.a.c.lib.Distinct class holds on to values in a local buffer, but doesn't deep
copy the values where necessary. This can lead to unexpected issues with the well-known object-reuse
bug, particularly if the same value is used by multiple DoFns.
