> 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

> 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.
