Hello Juili, This exception might happen if KubernetesIPFinder cannot connect a Kubernetes API server. It uses this address: https://github.com/apache/ignite/blob/master/modules/kubernetes/src/main/java/org/apache/ignite/spi/discovery/tcp/ipfinder/kubernetes/TcpDiscoveryKubernetesIpFinder.java#L113
Ensure that the address is discoverable. - Denis On Thu, Mar 12, 2020 at 1:37 AM Juili Bandgar <[email protected]> wrote: > Hello, > While creating ignite cluster in Kubernetes (v1.16.3), I am getting below > error multiple times: > > > [06:54:35] __________ ________________ > [06:54:35] / _/ ___/ |/ / _/_ __/ __/ > [06:54:35] _/ // (7 7 // / / / / _/ > [06:54:35] /___/\___/_/|_/___/ /_/ /___/ > [06:54:35] > [06:54:35] ver. 1.9.0#20170302-sha1:a8169d0a > [06:54:35] 2017 Copyright(C) Apache Software Foundation > [06:54:35] > [06:54:35] Ignite documentation: http://ignite.apache.org > [06:54:35] > [06:54:35] Quiet mode. > [06:54:35] ^-- Logging to file > '/opt/ignite/apache-ignite-fabric-1.9.0-bin/work/log/ignite-06ce7aa0.0.log' > [06:54:35] ^-- To see **FULL** console log here add -DIGNITE_QUIET=false > or "-v" to ignite.{sh|bat} > [06:54:35] > [06:54:35] OS: Linux 4.15.0-88-generic amd64 > [06:54:35] VM information: OpenJDK Runtime Environment > 1.8.0_111-8u111-b14-2~bpo8+1-b14 Oracle Corporation OpenJDK 64-Bit Server > VM > 25.111-b14 > [06:54:35] Configured plugins: > [06:54:35] ^-- None > [06:54:35] > [06:54:35] Message queue limit is set to 0 which may lead to potential > OOMEs > when running cache operations in FULL_ASYNC or PRIMARY_SYNC modes due to > message queues growth on sender and receiver sides. > [06:54:35] Security status [authentication=off, tls/ssl=off] > [06:54:36] Performance suggestions for grid (fix if possible) > [06:54:36] To disable, set -DIGNITE_PERFORMANCE_SUGGESTIONS_DISABLED=true > [06:54:36] ^-- Enable G1 Garbage Collector (add '-XX:+UseG1GC' to JVM > options) > [06:54:36] ^-- Set max direct memory size if getting 'OOME: Direct buffer > memory' (add '-XX:MaxDirectMemorySize=<size>[g|G|m|M|k|K]' to JVM options) > [06:54:36] ^-- Disable processing of calls to System.gc() (add > '-XX:+DisableExplicitGC' to JVM options) > [06:54:36] Refer to this page for more performance suggestions: > https://apacheignite.readme.io/docs/jvm-and-system-tuning > [06:54:36] > [06:54:36] To start Console Management & Monitoring run > ignitevisorcmd.{sh|bat} > [06:54:36] > [06:54:36] Ignite node started OK (id=06ce7aa0) > [06:54:36] Topology snapshot [ver=1, servers=1, clients=0, CPUs=6, > heap=1.0GB] > > [06:56:36,589][SEVERE][tcp-disco-ip-finder-cleaner-#4%null%][TcpDiscoverySpi] > Failed to clean IP finder up. > class org.apache.ignite.spi.IgniteSpiException: Failed to retrieve Ignite > pods IP addresses. > at > > org.apache.ignite.spi.discovery.tcp.ipfinder.kubernetes.TcpDiscoveryKubernetesIpFinder.getRegisteredAddresses(TcpDiscoveryKubernetesIpFinder.java:172) > at > > org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi.registeredAddresses(TcpDiscoverySpi.java:1613) > at > > org.apache.ignite.spi.discovery.tcp.ServerImpl$IpFinderCleaner.cleanIpFinder(ServerImpl.java:1801) > at > > org.apache.ignite.spi.discovery.tcp.ServerImpl$IpFinderCleaner.body(ServerImpl.java:1776) > at > org.apache.ignite.spi.IgniteSpiThread.run(IgniteSpiThread.java:62) > Caused by: java.net.ConnectException: Connection refused (Connection > refused) > at java.net.PlainSocketImpl.socketConnect(Native Method) > at > java.net > .AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) > at > java.net > .AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) > at > java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) > at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) > at java.net.Socket.connect(Socket.java:589) > at sun.security.ssl.SSLSocketImpl.connect(SSLSocketImpl.java:668) > at > sun.security.ssl.BaseSSLSocketImpl.connect(BaseSSLSocketImpl.java:173) > at sun.net.NetworkClient.doConnect(NetworkClient.java:180) > at sun.net.www.http.HttpClient.openServer(HttpClient.java:432) > at sun.net.www.http.HttpClient.openServer(HttpClient.java:527) > at > sun.net.www.protocol.https.HttpsClient.<init>(HttpsClient.java:264) > at sun.net.www.protocol.https.HttpsClient.New(HttpsClient.java:367) > at > > sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.getNewHttpClient(AbstractDelegateHttpsURLConnection.java:191) > at > > sun.net.www.protocol.http.HttpURLConnection.plainConnect0(HttpURLConnection.java:1138) > at > > sun.net.www.protocol.http.HttpURLConnection.plainConnect(HttpURLConnection.java:1032) > at > > sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:177) > at > > sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1546) > at > > sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1474) > at > > sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254) > at > > org.apache.ignite.spi.discovery.tcp.ipfinder.kubernetes.TcpDiscoveryKubernetesIpFinder.getRegisteredAddresses(TcpDiscoveryKubernetesIpFinder.java:153) > > > > > What are the reasons for the above problem?
