Hello everyone, I have developed a NRT Java app that indexes documents using a CloudSolrServer instance. During my tests I have a SolrCloud composed by only one shard and two Solr server instances. During the several tests I did found just in one case the following error: * * *12-11-20 12:54:03,609 3935290 [pool-1-thread-1-EventThread] ERROR org.apache.solr.common.cloud.ZkStateReader - * *org.apache.zookeeper.KeeperException$SessionExpiredException: KeeperErrorCode = Session expired for /clusterstate.json* * at org.apache.zookeeper.KeeperException.create(KeeperException.java:118)* * at org.apache.zookeeper.KeeperException.create(KeeperException.java:42)* * at org.apache.zookeeper.ZooKeeper.exists(ZooKeeper.java:815)* * at org.apache.solr.common.cloud.SolrZkClient$4.execute(SolrZkClient.java:193)* * at org.apache.solr.common.cloud.SolrZkClient$4.execute(SolrZkClient.java:190)* * at org.apache.solr.common.cloud.ZkCmdExecutor.retryOperation(ZkCmdExecutor.java:63) * * at org.apache.solr.common.cloud.SolrZkClient.exists(SolrZkClient.java:190) * * at org.apache.solr.common.cloud.ZkCmdExecutor.ensureExists(ZkCmdExecutor.java:90) * * at org.apache.solr.common.cloud.ZkCmdExecutor.ensureExists(ZkCmdExecutor.java:84) * * at org.apache.solr.common.cloud.ZkStateReader.createClusterStateWatchersAndUpdate(ZkStateReader.java:176) * * at org.apache.solr.common.cloud.ZkStateReader$1.command(ZkStateReader.java:144) * * at org.apache.solr.common.cloud.ConnectionManager$1.update(ConnectionManager.java:116) * * at org.apache.solr.common.cloud.DefaultConnectionStrategy.reconnect(DefaultConnectionStrategy.java:46) * * at org.apache.solr.common.cloud.ConnectionManager.process(ConnectionManager.java:90) * * at org.apache.zookeeper.ClientCnxn$EventThread.processEvent(ClientCnxn.java:526) * * at org.apache.zookeeper.ClientCnxn$EventThread.run(ClientCnxn.java:502)* *2012-11-20 12:54:07,052 3938733 [pool-1-thread-1-EventThread] ERROR org.apache.solr.common.cloud.DefaultConnectionStrategy - Reconnect to ZooKeeper failed:org.apache.solr.common.cloud.ZooKeeperException: * * at org.apache.solr.common.cloud.ZkStateReader$1.command(ZkStateReader.java:147) * * at org.apache.solr.common.cloud.ConnectionManager$1.update(ConnectionManager.java:116) * * at org.apache.solr.common.cloud.DefaultConnectionStrategy.reconnect(DefaultConnectionStrategy.java:46) * * at org.apache.solr.common.cloud.ConnectionManager.process(ConnectionManager.java:90) * * at org.apache.zookeeper.ClientCnxn$EventThread.processEvent(ClientCnxn.java:526) * * at org.apache.zookeeper.ClientCnxn$EventThread.run(ClientCnxn.java:502)* *Caused by: org.apache.zookeeper.KeeperException$SessionExpiredException: KeeperErrorCode = Session expired for /clusterstate.json* * at org.apache.zookeeper.KeeperException.create(KeeperException.java:118)* * at org.apache.zookeeper.KeeperException.create(KeeperException.java:42)* * at org.apache.zookeeper.ZooKeeper.exists(ZooKeeper.java:815)* * at org.apache.solr.common.cloud.SolrZkClient$4.execute(SolrZkClient.java:193)* * at org.apache.solr.common.cloud.SolrZkClient$4.execute(SolrZkClient.java:190)* * at org.apache.solr.common.cloud.ZkCmdExecutor.retryOperation(ZkCmdExecutor.java:63) * * at org.apache.solr.common.cloud.SolrZkClient.exists(SolrZkClient.java:190) * * at org.apache.solr.common.cloud.ZkCmdExecutor.ensureExists(ZkCmdExecutor.java:90) * * at org.apache.solr.common.cloud.ZkCmdExecutor.ensureExists(ZkCmdExecutor.java:84) * * at org.apache.solr.common.cloud.ZkStateReader.createClusterStateWatchersAndUpdate(ZkStateReader.java:176) * * at org.apache.solr.common.cloud.ZkStateReader$1.command(ZkStateReader.java:144) * * ... 5 more*
Probably it might be related with some kind of out memory unavailable issue, because I´m doing the tests in a very limitated machine, but maybe the origin is different and someone could tell me more about it. Thanks a lot in advance. Regards, -- - Luis Cappa
