Todd Lipcon updated HADOOP-7140:
--------------------------------
Attachment: hadoop-7140.txt
New rev of the patch:
- improves test assertions as suggested by Tom
- adds a try{}finally{} in the test so as to avoid causing problems if the test
fails
Tom and I discussed his idea about interrupts offline - we decided that using
interrupt() is a bit harsh since we don't want to catch a reader in the middle
of a readAndProcess(). Using selector.wakeup is cleaner.
> IPC Reader threads do not stop when server stops

> After HADOOP-6713, the new IPC "Reader" threads are not properly stopped when
> the server shuts down. One repercussion of this is that conditions that are
> supposed to shut down a daemon no longer work (eg the TT doesn't shut itself
> down if it detects an incompatible build version)
