[jira] Commented: (HADOOP-3264) libhdfs does not provide permissions in API

["Pete Wyckoff (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-3264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12628927#action_12628927 ] 

Pete Wyckoff commented on HADOOP-3264:
--------------------------------------

I now think the best thing is to go "posix-esque"

{code}

int chown(hdfsFS fs, const char *path, uid_t owner, gid_t group);
int chmod(hdfsFS fs, const char *path, mode_t mode)
int utime(hdfsFS fs, const char *filename, const struct utimbuf *buf);

{code}

Now, if we're worried that uid_t, gid_t, mode_t, utimebuf are not portable to windows cygwin or others, then we could just define our own versions of these, but probably to whatever extent possible, make them identical to posix ones.
