[ http://issues.apache.org/jira/browse/HADOOP-369?page=comments#action_12422050 ] Doug Cutting commented on HADOOP-369: -------------------------------------
I don't see why this needs to be a new generic FileSystem method. Can't it simply be a FileUtil method? Alternately, couldn't we just modify DFSShell.cat(String) to, when it's argument is a directory, recursively descend and copy all contained file content to standard output? Then one could just 'bin/hadoop dfs cat foo > bar' to append all content under 'foo' into a local file 'bar'. Would that work for you? > Added ability to copy all part-files into one output file > --------------------------------------------------------- > > Key: HADOOP-369 > URL: http://issues.apache.org/jira/browse/HADOOP-369 > Project: Hadoop > Issue Type: New Feature > Components: dfs > Affects Versions: 0.4.0 > Reporter: Johan Oskarson > Priority: Trivial > Attachments: copymerge.patch > > > Since we use the hadoop output in non-hadoop applications it's nice to be > able to merge the part-files into one output file on the local filesystem. > So I've added a dfsshell feature that streams from all files in a directory > to one output 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
