Jane Chen updated MAPREDUCE-3377: --------------------------------- Attachment: mapreduce-3377.patch > Compatibility issue with 0.20.203. > ---------------------------------- > > Key: MAPREDUCE-3377 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3377 > Project: Hadoop Map/Reduce > Issue Type: Bug > Affects Versions: 0.20.203.0, 1.0.0 > Environment: 0.20.203.0 standalone JDK 1.6 Linux > Reporter: Jane Chen > Assignee: Jane Chen > Attachments: mapreduce-3377.patch, mapreduce-3377.patch > > > I have an OutputFormat which implements Configurable. I set new config > entries to a job configuration during checkOutputSpec() so that the tasks > will get the config entries through the job configuration. This works fine > in 0.20.2, but stopped working starting from 0.20.203. With 0.20.203, my > OutputFormat still has the configuration set, but the copy a task gets does > not have the new entries that are set as part of checkOutputSpec(). > I believe that the problem is with JobClient. The job configuration needs to > wait till checkOutputSpec() is returned before being cloned and submitted. -- This message is automatically generated by JIRA.
