Hi there, I'm struggling with setting up a test implementation of SolrCloud using Vagrant.
I've got two vagrant boxes on a private network: * One Ubuntu machine running Zookeeper * One Ubuntu machine running Solr My zookeeper config is as follows: tickTime=4000 dataDir=/home/vagrant/zookeeper-data clientPort=2181 server.1=localhost:2888:3888 Zookeeper is running as expected. I’m starting it in foreground mode with the command below: bin/zkServer.sh start-foreground I’m then starting Solr in cloud mode: bin/solr start -c -z 172.28.128.3:2181 At this point, all seems well. Nothing bad shows up in the Solr logs, and no alarming messages coming through in the console for Zookeeper. I then try and create a collection with the command below: bin/solr create -c mycollection -d data_driven_schema_configs It’s then that I start seeing lots of errors in the Solr logs, and lots of repetitive messages appearing in Zookeeper: These two Solr errors over and over: java.io.IOException: Xid out of order. Got Xid 1299 with err 0 expected Xid 1298 for a packet with details: clientPath:null serverPath:null finished:false header:: 1298,14 replyHeader:: 0,0,-4 request:: org.apache.zookeeper.MultiTransactionRecord@95acc4f3 response:: org.apache.zookeeper.MultiResponse@0 There was a problem trying to register as the leader:org.apache.solr.common.SolrException: Could not register as the leader because creating the ephemeral registration node in ZooKeeper failed And this from Zookeeper: [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn$Factory@251] - Accepted socket connection from /172.28.128.4:54548 2016-08-21 21:33:39,137 - INFO [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@770] - Client attempting to renew session 0x156aefeba2d0004 at /172.28.128.4:54548 2016-08-21 21:33:39,145 - INFO [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@1580] - Established session 0x156aefeba2d0004 with negotiated timeout 15000 for client /172.28.128.4:54548 2016-08-21 21:33:39,147 - WARN [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:ZooKeeperServer@593] - Dropping packet at server of type 14 2016-08-21 21:33:39,154 - WARN [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@634] - EndOfStreamException: Unable to read additional data from client sessionid 0x156aefeba2d0004, likely client has closed socket 2016-08-21 21:33:39,155 - INFO [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@1435] - Closed socket connection for client /172.28.128.4:54548 which had sessionid 0x156aefeba2d0004 2016-08-21 21:33:40,698 - INFO Finally, the collection creation fails with the following message: ERROR: Failed to create collection 'mycollection' due to: create the collection time out:180s I can't find any useful references to these errors in SO or in the docs. Can anyone help me diagnose the problem?
