Subject Re: 答复: ignite Connection refused exception
Date Thu, 21 Jul 2016 11:09:41 GMT
Hi Kevin,

The last error message suggests that it was a problem when trying to
establish communication between two nodes on the same machine using shared
memory mechanics. It is not clear now what is the reason for this, but I
would try to disable shared memory and see if it helps.

In XML file please add the following bean:

<bean id="ignite.cfg"
class="org.apache.ignite.configuration.IgniteConfiguration">
    ...
    <property name="communicationSpi">
        <bean class="org.apache.ignite.spi.communication.tcp.TcpCommunicationSpi">
            <property name="sharedMemoryPort" value="-1"/>
        </bean>
    </property>
    ....
</bean>


And add the following line to your programmatic configuration:

TcpCommunicationSpi commSpi = new TcpCommunicationSpi();
*commSpi.setSharedMemoryPort(-1); *

igniteCCF.setCommunicationSpi(commSpi);

Please let me know if it resolves the problem. Otherwise please attach the
whole logs from all nodes.

Vladimir.
