Todd Lipcon updated HADOOP-8228:
--------------------------------
Attachment: hadoop-8228.txt
New rev includes code which covers the retry-on-disconnect mechanisms in the
elector, as well as many of the error handling paths. While running a stress
test, it has the ZK server disconnect all of its clients every 50ms. This
causes outstanding ZK calls to get a {{Disconnected}} error and have to handle
it.
I verified with Clover that this covers the retry code paths and various
failure cases while writing/reading the breadcrumb node, etc.

> It's important that the ZKFailoverController be robust and not contain race
> conditions, etc. One strategy to find potential races is to add stress tests
> which exercise the code as fast as possible. This JIRA is to implement some
> test cases of this style.
