Anatolii Botov updated IGNITE-11222:
------------------------------------
Ignite Flags: (was: Docs Required)
> TcpDiscoverySpi stops listen port on network timeout
> ----------------------------------------------------
>
> Key: IGNITE-11222
> URL: https://issues.apache.org/jira/browse/IGNITE-11222
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.7
> Environment: OS: Ubuntu 18.04, Centos 7
> Ignite runs as part of application through Ignition.start()
>
>
> Reporter: Anatolii Botov
> Priority: Major
> Attachments: ignite_logs.zip

> I've created cluster from 2 nodes.
> I've configured them as follow:
>
> {code:java}
> val config = new IgniteConfiguration()
> val discoverySpi = new TcpDiscoverySpi
> discoverySpi.setLocalAddress(discoveryAddress.getHostString)
> discoverySpi.setLocalPort(discoveryAddress.getPort)
> val ipFinder = new TcpDiscoveryVmIpFinder()
> ipFinder.setAddresses(ipAddresses.asJava)
> discoverySpi.setIpFinder(ipFinder)
> config.setDiscoverySpi(discoverySpi)
> val commSpi = new TcpCommunicationSpi()
> commSpi.setLocalAddress(communicationAddress.getHostString)
> commSpi.setLocalPort(communicationAddress.getPort)
> commSpi.setSlowClientQueueLimit(igniteConf.getInt("slow-client-queue-limit").getOrElse(1000))
> commSpi.setMessageQueueLimit(
>
> igniteConf.getInt("message-queue-limit").getOrElse(TcpCommunicationSpi.DFLT_MSG_QUEUE_LIMIT)
> )
> config.setCommunicationSpi(commSpi)
> config.setSegmentationPolicy(SegmentationPolicy.NOOP)
> {code}
>
>
> * For first node(10.84.0.120) values are:
> {code:java}
> val discoveryAddress = 0.0.0.0:47500
> val communicationAddress = 0.0.0.0:47600
> val ipAddresses = Seq("127.0.0.1"){code}
> * For second node(10.84.13.131) values are:
> {code:java}
> val discoveryAddress = 0.0.0.0:47500
> val communicationAddress = 0.0.0.0:47600
> val ipAddresses = Seq("10.84.0.120:47500"){code}
>
> 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:
> {code:java}
> iptables -A OUTPUT -d 10.84.0.120 -j DROP{code}
> Unblocking:
> {code:java}
> iptables -D OUTPUT -d 10.84.0.120 -j DROP{code}
>
> 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.
