+If no permissions are specified, the newly created file will be assigned with default 755 permission. This also applies for new directories. No umask mode will be applied from server side (so "fs.permissions.umask-mode" value configuration set on Namenode side will have no effect).

**Note** that the reason of having two-step create/append is for preventing clients to send out data before the redirect. This issue is addressed by the "`Expect: 100-continue`" header in HTTP/1.1; see [RFC 2616, Section 8.2.3](http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.2.3). Unfortunately, there are software library bugs (e.g. Jetty 6 HTTP server and Java 6 HTTP client), which do not correctly implement "`Expect: 100-continue`". The two-step create/append is a temporary workaround for the software library bugs.
