Hi,
Following error is very commonly seen in Solr. Does anybody know why that is so? And is it asking the user to do something about it? org.apache.solr.common.SolrException: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /collections/my-valid-collection/state.json at org.apache.solr.handler.admin.ZookeeperInfoHandler$ZKPrinter.writeError(ZookeeperInfoHandler.java:544) at org.apache.solr.handler.admin.ZookeeperInfoHandler$ZKPrinter.printZnode(ZookeeperInfoHandler.java:812) at org.apache.solr.handler.admin.ZookeeperInfoHandler$ZKPrinter.print(ZookeeperInfoHandler.java:526) at org.apache.solr.handler.admin.ZookeeperInfoHandler.handleRequestBody(ZookeeperInfoHandler.java:414) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:177) at org.apache.solr.servlet.HttpSolrCall.handleAdmin(HttpSolrCall.java:735) at org.apache.solr.servlet.HttpSolrCall.handleAdminRequest(HttpSolrCall.java:716) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:497) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:382) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:326) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1751) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:582) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:548) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:226) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1180) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:512) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:185) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1112) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:213) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:119) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:134) at org.eclipse.jetty.rewrite.handler.RewriteHandler.handle(RewriteHandler.java:335) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:134) at org.eclipse.jetty.server.Server.handle(Server.java:534) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:320) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:251) at org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:283) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:108) at org.eclipse.jetty.io.SelectChannelEndPoint$2.run(SelectChannelEndPoint.java:93) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.executeProduceConsume(ExecuteProduceConsume.java:303) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.produceConsume(ExecuteProduceConsume.java:148) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.run(ExecuteProduceConsume.java:136) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:671) at org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:589) at java.lang.Thread.run(Thread.java:745) Thanks SG
