I'm installing SolrCloud 5.2.1 on 4 Ubuntu 14.04 machines with 3 external zookeepers. I've installed the solr machines using Ansible following the "Taking Solr to Production" steps.
1. Download 5.2.1 2. Extract installation script 3. Run installation script Then I stop solr and make my configuration changes to the solr.in.sh file (adding zookeepers) and log4j.properties (recommended changes). Restart solr and everything looks good. The problem I have is that I can't create a collection. I create the collection folder in /var/solr/data and tried both the bin script and API but get the error below. I've tried 5.2.0 also and both Java 7 and 8 with the same result. 50047java.io.InvalidClassException: org.apache.solr.client.solrj.SolrResponse; local class incompatible: stream classdesc serialVersionUID = 3123208377723774018, local class serialVersionUID = 3945300637328478755org.apache.solr.common.SolrException: java.io.InvalidClassException: org.apache.solr.client.solrj.SolrResponse; local class incompatible: stream classdesc serialVersionUID = 3123208377723774018, local class serialVersionUID = 3945300637328478755 at org.apache.solr.client.solrj.SolrResponse.deserialize(SolrResponse.java:62) at org.apache.solr.handler.admin.CollectionsHandler.handleResponse(CollectionsHandler.java:228) at org.apache.solr.handler.admin.CollectionsHandler.handleRequestBody(CollectionsHandler.java:168) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:143) at org.apache.solr.servlet.HttpSolrCall.handleAdminRequest(HttpSolrCall.java:646) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:417) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:227) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:196) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1652) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:585) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:577) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:223) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1127) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:515) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:185) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1061) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:215) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:110) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:97) at org.eclipse.jetty.server.Server.handle(Server.java:497) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:310) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:257) at org.eclipse.jetty.io.AbstractConnection$2.run(AbstractConnection.java:540) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:635) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:555) at java.lang.Thread.run(Thread.java:745) Caused by: java.io.InvalidClassException: org.apache.solr.client.solrj.SolrResponse; local class incompatible: stream classdesc serialVersionUID = 3123208377723774018, local class serialVersionUID = 3945300637328478755 at java.io.ObjectStreamClass.initNonProxy(ObjectStreamClass.java:617) at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1622) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1517) at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1622) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1517) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1771) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1350) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:370) at org.apache.solr.client.solrj.SolrResponse.deserialize(SolrResponse.java:60) ... 27 more 500
