> cluster_manager will start a cluster on a set of host:port URLs that you specify on the command line.
> The hosts can all be different -- so long as they are all clustered and have openais running on them.
> It will then periodically check the qpid cluster and make sure that there are syill brokers running at the expected places.
> ( For this, it uses ssh and reads /proc . )
> If it finds that one or more brokers are missing, it will start new brokers to replace them.
> This will allows us to run long-term tests in which the clients start and stop (or are killed) during the test -- they will always know what set of host:ports to attach to. Clients can be written either to try one host:port after the other until they connect (which is functionality available from the client library) -- or so that they try a single host:port -- then wait 30 seconds or so and retry if it doesn't work the first time.
> ( Because of the use of ssh, this is not a very high-speed application. It often takes more than 30 seconds to check on a cluster of 3 brokers. )
