Hello,
We are facing a critical issue with Ignite 2.8.
We have two machines in same location running different ignite services.
M1
Ignite server (running on port 48500)
Ignite client-1 (running on port 48100)
M2
Ignite client-2 (running on port 14050)
Port opened between machines:
M2 to M1 - 48500-48520, 48100-48200
M1 to M2 - 14050
Now, M2 is not able to connect to ignite cluster if I set
usePairedConnections to true.
If I have usePairedConnections to false in TCPCommunicationSPI then all
works fine.
Here is the related ignite config:
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="joinTimeout" value="15000" />
<property name="ClientReconnectDisabled" value="true" />
<property name="localPort" value="48500" />
<property name="localPortRange" value="20" />
<property name="ipFinder">
<bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder">
<property name="addresses">
<list>
<value>hkvaspsy-101:48500..48520</value>
</list>
</property>
</bean>
</property>
</bean>
</property>
<property name="communicationSpi">
<bean id="communicationSpiBean"
class="org.apache.ignite.spi.communication.tcp.TcpCommunicationSpi">
<property name="localPort" value="48100" />
<property name="slowClientQueueLimit" value="100000" />
<property name="idleConnectionTimeout" value="30000" />
<property name="usePairedConnections" value="true" />
</bean>
</property>
Connection refused is noticed in the logs on ignite client-2.

Could you please tell why it is failing in case usePairedConnection is set
to true?
Do we also need 48100-48200 ports opened from M1 to M2 as well?
Thanks.
