Himanshu Vashishtha commented on HBASE-6699:
--------------------------------------------
yes, the username is tied to the Connection.
There is one extra rpc, to set/tie the username to the Connection, and is
issued after sending the ConnectionHeader. It will be send one time whenever a
connection is created (I will make it optional though, as Stack said). Its a
non-blocking call to the server.
With the first approach I mentioned, we could have set it in the
ConnectionHeader itself and avoided any extra rpc, but it will be a change in a
Writable.

> We recently had a requirement where we need to log the information about
> various users who were using non-secure HBase cluster.
> The user level logging is supported as part of security, but in 0.92, 0.94
> security related code is separate. This jira is about adding that support in
> non-secure code.
> This feature is already there in trunk, after we merge the security related
> code.
