Raghu Angadi updated HADOOP-1961: --------------------------------- Attachment: HADOOP-1961.patch Updated patch for trunk. If we want to retain the partially copied file, then fix I would suggest is to remove 'deleteOnExit' flag for the tmp file. > -get, -copyToLocal fail when single filename is passed > ------------------------------------------------------- > > Key: HADOOP-1961 > URL: https://issues.apache.org/jira/browse/HADOOP-1961 > Project: Hadoop > Issue Type: Bug > Components: dfs > Affects Versions: 0.14.1 > Reporter: Koji Noguchi > Assignee: Raghu Angadi > Priority: Blocker > Fix For: 0.14.2 > > Attachments: HADOOP-1961-branch14.patch, HADOOP-1961.patch, > HADOOP-1961.patch, HADOOP-1961.patch > > > In 0.14.1 and in trunk, when I try > % hadoop dfs -get /user/knoguchi/aaa aaa > get: Failed to rename tmp file to local destination "aaa". Remote source > file "/user/knoguchi/aaa" is saved to "/tmp/_copyToLocal_aaa30478". > This works. > % hadoop dfs -get /user/knoguchi/aaa ./aaa > or > % hadoop dfs -get /user/knoguchi/aaa /home/knoguchi/aaa > My guess. With change in HADOOP-1292, it now creates a tmp file when > -copyToLocal. > When destination path is passed without any directory, tmp file is created > under '/tmp'. Otherwise, it uses the same directory as the destination path. > In Java API for File.renameTo, > http://java.sun.com/javase/6/docs/api/java/io/File.html#renameTo(java.io.File) > it says > " The rename operation might not be able to move a file from one filesystem > to another", > so renameTo call from /tmp/_tmpfile to /home/knoguchi can fail. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
