Hi Denis,
I have configured TcpDiscoverySpi both on the server side and client side.
On the server side, my configuration is as follows:
<property name="discoverySpi">
<bean
class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="ipFinder">
<bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder">
<property name="addresses">
<list>
<value>10.120.70.122:47500..47509</value>
<value>10.120.89.196:47500..47509</value>
</list>
</property>
</bean>
</property>
</bean>
</property>
On the client side, I am using java to configure the cache, here is the code:
TcpDiscoveryVmIpFinder ipFinder = new TcpDiscoveryVmIpFinder(false);
List<String> addrs = new ArrayList<String>();
addrs.add(IGNITE_NEW_ADDRESS);
addrs.add(IGNITE_ADDRESS);
ipFinder.setAddresses(addrs);
TcpDiscoverySpi discoverySpi = new TcpDiscoverySpi();
discoverySpi.setIpFinder(ipFinder);
// discoverySpi.setLocalAddress(instanceName);
// discoverySpi.setLocalPort(47505);
igniteCCF.setDiscoverySpi(discoverySpi);
TcpCommunicationSpi commSpi = new TcpCommunicationSpi();
igniteCCF.setCommunicationSpi(commSpi);
//create ignite instance
ignite = Ignition.start(igniteCCF);
But I still cannot connect to the server. Or I should see, it did connected to
the server, however, closed without communication.
When I check the server console, I can see the client node joined, but return
the following error:

Any Idea how to fix it?

主题: Re: ignite Connection refused exception
Hi Kevin,
The exception means that the connection was rejected on a remote side (server
side). Please make sure that discovery SPI ports are opened between the server
and client and that the client connects to a valid server node (the server node
must listen for incoming connection in one of the ports specified in client’s
IP finder configuration).

Hi there,
When using ignite client connect to the server, I always get exceptions like
