I've created cluster from 2 nodes.

I've configured them as follow:

{color:#000080}val {color}config = {color:#000080}new {color}IgniteConfiguration()


 {color:#000080}val {color}discoverySpi = {color:#000080}new {color}TcpDiscoverySpi
discoverySpi.setLocalAddress(discoveryAddress.getHostString)
discoverySpi.setLocalPort(discoveryAddress.getPort)

{color:#000080}val {color}ipFinder = {color:#000080}new {color}TcpDiscoveryVmIpFinder()
ipFinder.setAddresses(ipAddresses.asJava)

discoverySpi.setIpFinder(ipFinder)
config.setDiscoverySpi(discoverySpi)

{color:#000080}val {color}commSpi = {color:#000080}new {color}TcpCommunicationSpi()
commSpi.setLocalAddress(communicationAddress.getHostString)
commSpi.setLocalPort(communicationAddress.getPort)
commSpi.setSlowClientQueueLimit(igniteConf.getInt({color:#008000}"slow-client-queue-limit"{color}).getOrElse({color:#0000ff}1000{color}))
commSpi.setMessageQueueLimit(
 igniteConf.getInt({color:#008000}"message-queue-limit"{color}).getOrElse(TcpCommunicationSpi.{color:#660e7a}DFLT_MSG_QUEUE_LIMIT{color})
)
config.setCommunicationSpi(commSpi)

config.setSegmentationPolicy(SegmentationPolicy.{color:#660e7a}NOOP{color})

 For first node(10.84.13.131) values are:
 {color:#000080}val {color}discoveryAddress = 0.0.0.0:47500
 {color:#000080}val {color}communicationAddress = 0.0.0.0:47600
 {color:#000080}val {color}ipAddresses = {color:#660e7a}Seq{color}({color:#008000}"127.0.0.1"{color})

 

For second node(10.84.0.120) values are:
 {color:#000080}val {color}discoveryAddress = 0.0.0.0:47500
 {color:#000080}val {color}communicationAddress = 0.0.0.0:47600
 {color:#000080}val {color}ipAddresses = {color:#660e7a}Seq{color}({color:#008000}"10.84.0.120:47500"{color})

 

After i start first node and the second second connects to first and everything is OK. Then i block traffic from first node to second:

iptables -A OUTPUT -d 10.84.0.120 -j DROP

 

There is 2 cases:
 # if traffic is blocked more than default timeout in ignite config, everything works as expected: split brain.
 # But if i remove blocking before timeout is almost expired. Then first node closes socket on port 47500 and becomes unreachable for further reconnection attempts from first node.
