Re: Client reconnect problems
Mario,
Although client discovery is in code it has never been announced. It will
be dropped in the upcoming release and client mode will appear for ordinary
tcp disco.
As far as reconnection - you raised a very good question. It is currently
under development in new API and will be available soon.
For now please go on with TcpDiscoverySpi.

Hi list!
I started to use Ignite (1.1.0-incubating) for a network message bus where
I have a server node and several client nodes using the
TcpClientDiscoverySpi.
On first startup, it does not matter in which order I start my Ignite
sever or client. Each other waits as expected to have the grid running. But
if I kill the server, the client fails to reconnect to it.
I have a simple test for this.
Just start the class TestIgniteClient with program parameter „s“ and again
with „c“ so you have two instances running. Then you should see the message
„I am here“ flowing from the server to the client.
Once you kill the server process („s“) and restart it, you will get a lot
of exception on the client and it will not reconnect.
Is there something I do wrong, or should I file a JIRA about that?
Thanks for your help.
