[TcpDiscoverySpi] Failed to connect to any address from IP finder

[Chetan Jayaram]

Hello,



I am aware that this issue has been discussed in this forum in past. But
none of the resolution steps given helped resolve this.

I am facing the below issues ;



   1. Apache Ignite version  2.6.0, [ issue occurs in versions 2.5.0, 2.4.0
   ]

IntelliJ

Spark-scala

Machine : standalone laptop.

OS : Windows.



2. Error  :  Failed to connect to any address from IP finder

127.0.0.1:47508, /127.0.0.1:47509]



I am able to successfully execute it from the cmdline and it works fine,
but when I try to execute this from Intellij (IDE) via the 'scala'
application code.

I tried couple of resolution steps, like fetching the
InetAddress.getLocalHost etc



import org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi

import
org.apache.ignite.spi.discovery.tcp.ipfinder.multicast.TcpDiscoveryMulticastIpFinder

import
org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder

import java.util.Collections

import org.apache.ignite.configuration.IgniteConfiguration

val nodeHost = InetAddress.getLocalHost.getHostName

val port = "47500"

val spi = new TcpDiscoverySpi

val ipFinder = new TcpDiscoveryMulticastIpFinder

ipFinder.setLocalAddress(nodeHost+ ':' + port)

   // ipFinder.setAddresses(Collections.singletonList(nodeHost + ':' +
port))

spi.setIpFinder(ipFinder)

val cfg = new IgniteConfiguration()

cfg.setDiscoverySpi(spi)



interestingly this is similar to adding the IP address in the
default-config.xml  and also the usual 127.0.0.1 but it still doesn’t work.



   <property name="discoverySpi">

            <bean
class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">

                <property name="ipFinder">

                    <!--

                        Ignite provides several options for automatic
discovery that can be used

                        instead os static IP based discovery. For
information on all options refer

                        to our documentation:

                    -->

                    <!-- Uncomment static IP finder to enable static-based

                    <bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder">

                        <property name="addresses">

                            <list>

                                <!-- In distributed environment, replace
with actual host IP address. -->

                                <value><my ip address> :47500..47509</value>

                            </list>

                        </property>

                    </bean>

                </property>

            </bean>

        </property>



I have tried both approaches, the code and also the default-config.xml.
Interestingly these parameters are optional  and I am executing this in my
standalone laptop.

Kindly provide resolution to fix this error. Is this a window-specifc
issue, but I am able to execute from the command console.
