Andrew Sherman commented on HIVE-16917:
---------------------------------------
A single connection can result in multiple threads. So could you make a
denial-of-service attack using a single connection? Connections would then fail
after the number of client connections is greater than
hive.server2.thrift.max.worker.threads.

> HS2 should start rejecting the number of connections from a user, after it
