Patch looks good overall. I think we can significantly reduce the size of the testcase file since the problem occurs early in it. I noticed that if we cut the file down to just 530 records instead of 20,000 records and compress with bzip2 -1 it still catches the failure but is only a 10K binary rather than a 409K binary. > 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.
