-Re: hdfs -copyToLocal file permission

No, permissions are not preserved. FsShell copy commands match *nix's cp behavior by using the current umask (the conf setting you cited) for the permissions of new file. Perhaps we could add a -p option, like the *nix cp, to preserve permissions. In the meantime you can set the umask if most of your files have the same permissions.

While copying file from hdfs file permissions are getting changed, my assumption was that while copying permissions should be retained. Is this behavior correct ?

fs.permissions.umask-mode is not set so I think it defaults to 0022
