[ http://issues.apache.org/jira/browse/HADOOP-611?page=comments#action_12448220 ] Owen O'Malley commented on HADOOP-611: --------------------------------------
I don't understand the ignoreSync, doSync code that you have in the the SegmentDescriptor. You should never set the sync = null on a Reader. It is done on merge outputs via writer.sync = null to keep the writer from putting in sync blocks, which wastes space since the merge outputs won't be split as map inputs. But setting sync = null on a reader shouldn't be necessary. > SequenceFile.Sorter should have a merge method that returns an iterator > ----------------------------------------------------------------------- > > Key: HADOOP-611 > URL: http://issues.apache.org/jira/browse/HADOOP-611 > Project: Hadoop > Issue Type: New Feature > Components: io > Reporter: Owen O'Malley > Assigned To: Devaraj Das > Fix For: 0.9.0 > > Attachments: merge.patch, merge.patch, merge.patch, merge.patch > > > SequenceFile.Sorter should get a new merge method that returns an iterator > over the keys/values. > The current merge method should become a simple method that gets the iterator > and writes the records out to a file. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
