David Ciemiewicz commented on MAPREDUCE-469: -------------------------------------------- Greg, I have yet to encounter ANYONE who doesn't consider this a bug because all cited reference EXPECT concatenated files to work because the work in ALL OTHER cited instances including gnu tools, web browsers, etc. Can you think of a single instance where it would be the right thing to stop reading a concatenated file after the first part is read, ignoring all other concatenated parts. Forgive me but suggesting that we keep the existing behavior seems absurd because I cannot think of a single case where this would be the right thing to do. > Support concatenated gzip and bzip2 files > ----------------------------------------- > > Key: MAPREDUCE-469 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-469 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Reporter: Tom White > Assignee: Greg Roelofs > Attachments: grr-hadoop-common.dif.20100614c, > grr-hadoop-mapreduce.dif.20100614c > > > When running MapReduce with concatenated gzip files as input only the first > part is read, which is confusing, to say the least.
