Wilfred Spiegelenburg updated MAPREDUCE-6558: --------------------------------------------- Attachment: MAPREDUCE-6558.1.patch A patch with test input that fails before the fix was made and passes after the fix was made. I have run all the tests that were there and they all still pass with this change. The tests have been run a large number of times with different input splits and none of them have failed. The use cases that passed before the fix was applied have been documented in the code. > multibyte delimiters with compressed input files generate duplicate records > --------------------------------------------------------------------------- > > Key: MAPREDUCE-6558 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6558 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv1, mrv2 > Affects Versions: 2.7.2 > Reporter: Wilfred Spiegelenburg > Assignee: Wilfred Spiegelenburg > Attachments: MAPREDUCE-6558.1.patch > > > This is the follow up for MAPREDUCE-6549.
