Steve Loughran updated HADOOP-6221:
-----------------------------------
Attachment: HADOOP-6221.patch
Tests show this problem is harder than it appears, even with improved Interrupt
support during the sleep(), you can't interrupt the client while it is actually
waiting to connect, that gets swallowed somewhere too. The test case shows
this; a thread that tries to wait for 20s for a connection, but which is
interrupted in another thread never sees the interrupt, instead after 20s it
times out and throws the ConnectionRefused fault. What I'd like would be the
interrupt acknowledged with the inner exception nested, and for the operation
to fail as soon as the thread is interrupted.

>
> RPC.waitForProxy swallows any attempts to interrupt it while waiting for a
> proxy; this makes it hard to shutdown a service that you are starting; you
> have to wait for the timeouts.
> There are only 4-5 places in the code that use either of the two overloaded
> methods, removing the catch and changing the signature should not be too
> painful, unless anyone is using the method outside the hadoop codebase.
