Hi all, in my solr cloud one of the nodes is not connecting anymore I get the error message
"LeaderElector node exists" every second.. The log files says: 2021-04-12 13:43:12.195 INFO (zkCallback-14-thread-29) [ ] o.a.s.c.OverseerElectionContext I am going to be the leader gmpg-services8.mpiwg-berlin.mpg.de <http://gmpg-services8.mpiwg-berlin.mpg.de/>:58989_solr 2021-04-12 13:43:12.230 ERROR (zkCallback-14-thread-29) [ ] o.a.s.c.LeaderElector node exists => org.apache.zookeeper.KeeperException$NodeExistsException: KeeperErrorCode = NodeExists for /overseer_elect/leader at org.apache.zookeeper.KeeperException.create(KeeperException.java:126) org.apache.zookeeper.KeeperException$NodeExistsException: KeeperErrorCode = NodeExists for /overseer_elect/leader at org.apache.zookeeper.KeeperException.create(KeeperException.java:126) ~[?:?] at org.apache.zookeeper.KeeperException.create(KeeperException.java:54) ~[?:?] at org.apache.zookeeper.ZooKeeper.create(ZooKeeper.java:1734) ~[?:?] at org.apache.solr.common.cloud.SolrZkClient.lambda$makePath$10(SolrZkClient.java:542) ~[?:?] at org.apache.solr.common.cloud.ZkCmdExecutor.retryOperation(ZkCmdExecutor.java:71) ~[?:?] at org.apache.solr.common.cloud.SolrZkClient.makePath(SolrZkClient.java:541) ~[?:?] at org.apache.solr.common.cloud.SolrZkClient.makePath(SolrZkClient.java:485) ~[?:?] at org.apache.solr.common.cloud.SolrZkClient.makePath(SolrZkClient.java:472) ~[?:?] at org.apache.solr.cloud.OverseerElectionContext.runLeaderProcess(OverseerElectionContext.java:65) ~[?:?] at org.apache.solr.cloud.LeaderElector.runIamLeaderProcess(LeaderElector.java:172) ~[?:?] at org.apache.solr.cloud.LeaderElector.checkIfIamLeader(LeaderElector.java:138) ~[?:?] at org.apache.solr.cloud.LeaderElector.access$200(LeaderElector.java:58) ~[?:?] at org.apache.solr.cloud.LeaderElector$ElectionWatcher.process(LeaderElector.java:350) ~[?:?] at org.apache.solr.common.cloud.SolrZkClient$ProcessWatchWithExecutor.lambda$process$1(SolrZkClient.java:892) ~[?:?] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) ~[?:1.8.0_282] at java.util.concurrent.FutureTask.run(FutureTask.java:266) ~[?:1.8.0_282] at org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor.lambda$execute$0(ExecutorUtil.java:218) ~[?:?] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) ~[?:1.8.0_282] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) ~[?:1.8.0_282] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_282] I am not sure if this is connected: One of my zookeeper crashed before and I had to restart it, the folder with snapshot.* and log.* where not readable anymore and I had to create a new one. Any help would be very much appreciated. Cheers Dirk -------------------------------------- -------------------------------------- Dr.-Ing.
