Subject [jira] [Commented] (HBASE-8662) [rest] support impersonation
Date Wed, 19 Jun 2013 23:42:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13688651#comment-13688651

Jimmy Xiang commented on HBASE-8662:
------------------------------------

This is a trade-off.  Proxy user per context needs to maintain connections per context.  Proxy
user per method needs to maintain one connection, but needs to authorize the user, send user
information to server for every call because HBase server side may have authorization setup
too.  The first solution is good for tiny number of users for many many requests per user.
 The second solution is good for large number of users to make small number of requests per
user.

> Currently, our client API uses a fixed user: the current user. It should accept a user
passed in, if authenticated.
