Doug Cutting commented on HADOOP-175: ------------------------------------- > I could add similar main() methods to SequenceFile.Reader and MapFile.Reader > ... Yes, please! Also, the OutputFormat versions could call routines from these, no? They would mostly be directory iterators, right, but could use the primitive MapFile & SequenceFile to dump records. > Utilities for reading SequenceFile and MapFile > ---------------------------------------------- > > Key: HADOOP-175 > URL: http://issues.apache.org/jira/browse/HADOOP-175 > Project: Hadoop > Type: Improvement > Components: io > Reporter: Andrzej Bialecki > Priority: Minor > Attachments: patch.txt > > Most data in Hadoop is stored in SequenceFile-s and MapFile-s. Sometimes > there is a need to examine such files, but no specialized utilities exist ro > read them. > These two classes provide a functionality to examine individual records in > such files, and also to dump the content of such files to a plain text output. -- 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
