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.
