Amareshwari Sriramadasu resolved MAPREDUCE-450. ----------------------------------------------- Resolution: Duplicate This functionality is provided by OutputCommitter. See HADOOP-3150 > OutputFormat should have a "close" method called after all the reducers have > completed > -------------------------------------------------------------------------------------- > > Key: MAPREDUCE-450 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-450 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Reporter: Nathan Marz > Priority: Minor > > It would be very useful for OutputFormat's to have a "close" method so that > any global logic for outputting can take place there. For example, to output > a meta data file along with all the reduce outputs. The close method should > have the following signature and be run after all the reducers have finished, > but before the "work output path" is renamed to the final output path: > void close(FileSystem fs, JobConf job, Progressable progress) throws > IOException -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
