Hi, running an elasticsearch cluster version 2.3.1 with one master, three data nodes and one client node on kubernetes, the last node is exposing the 9200 rest port. All other nodes just have the 9300 cluster port exposed. Cluster is working fine for logstash logs. If I try to get /\_nodes/stats I get [WARN][rest.suppressed] /\_nodes/stats Params: {all=true} java.lang.ClassCastException Any idea why it is not working? Regards, Olaf [2016-05-18 11:32:58,003][WARN][rest.suppressed] /\_nodes/stats Params: {all=true} java.lang.ClassCastException: org.elasticsearch.action.admin.indices.stats.CommonStatsFlags cannot be cast to [Ljava.lang.String; at org.elasticsearch.plugin.readonlyrest.acl.RequestContext$1.run(RequestContext.java:63) at org.elasticsearch.plugin.readonlyrest.acl.RequestContext$1.run(RequestContext.java:46) at java.security.AccessController.doPrivileged(Native Method) at org.elasticsearch.plugin.readonlyrest.acl.RequestContext.getIndices(RequestContext.java:45) at org.elasticsearch.plugin.readonlyrest.acl.blocks.rules.impl.KibanaAccessRule.match(KibanaAccessRule.java:107) at org.elasticsearch.plugin.readonlyrest.acl.blocks.Block.check(Block.java:112) at org.elasticsearch.plugin.readonlyrest.acl.ACL.check(ACL.java:46) at org.elasticsearch.plugin.readonlyrest.IndexLevelActionFilter.apply(IndexLevelActionFilter.java:82) at org.elasticsearch.action.support.ActionFilter$Simple.apply(ActionFilter.java:64) at org.elasticsearch.action.support.TransportAction$RequestFilterChain.proceed(TransportAction.java:170) at org.elasticsearch.action.support.TransportAction.execute(TransportAction.java:144) at org.elasticsearch.action.support.TransportAction.execute(TransportAction.java:85) at org.elasticsearch.client.node.NodeClient.doExecute(NodeClient.java:58) at org.elasticsearch.client.support.AbstractClient.execute(AbstractClient.java:359) at org.elasticsearch.client.FilterClient.doExecute(FilterClient.java:52) at org.elasticsearch.rest.BaseRestHandler$HeadersAndContextCopyClient.doExecute(BaseRestHandler.java:83) at org.elasticsearch.client.support.AbstractClient.execute(AbstractClient.java:359) at org.elasticsearch.client.support.AbstractClient$ClusterAdmin.execute(AbstractClient.java:853) at org.elasticsearch.client.support.AbstractClient$ClusterAdmin.nodesStats(AbstractClient.java:948) at org.elasticsearch.rest.action.admin.cluster.node.stats.RestNodesStatsAction.handleRequest(RestNodesStatsAction.java:109) at org.elasticsearch.rest.BaseRestHandler.handleRequest(BaseRestHandler.java:54) at org.elasticsearch.rest.RestController.executeHandler(RestController.java:205) at org.elasticsearch.rest.RestController$RestHandlerFilter.process(RestController.java:279) at org.elasticsearch.rest.RestController$ControllerFilterChain.continueProcessing(RestController.java:260) at org.elasticsearch.plugin.readonlyrest.ReadonlyRestAction$1.process(ReadonlyRestAction.java:39) at org.elasticsearch.rest.RestController$ControllerFilterChain.continueProcessing(RestController.java:263) at org.elasticsearch.rest.RestController.dispatchRequest(RestController.java:176) at org.elasticsearch.http.HttpServer.internalDispatchRequest(HttpServer.java:128) at org.elasticsearch.http.HttpServer$Dispatcher.dispatchRequest(HttpServer.java:86) at org.elasticsearch.http.netty.NettyHttpServerTransport.dispatchRequest(NettyHttpServerTransport.java:449) at org.elasticsearch.http.netty.HttpRequestHandler.messageReceived(HttpRequestHandler.java:61) at org.jboss.netty.channel.SimpleChannelUpstreamHandler.handleUpstream(SimpleChannelUpstreamHandler.java:70) at org.jboss.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:564) at org.jboss.netty.channel.DefaultChannelPipeline$DefaultChannelHandlerContext.sendUpstream(DefaultChannelPipeline.java:791) at org.elasticsearch.http.netty.pipelining.HttpPipeliningHandler.messageReceived(HttpPipeliningHandler.java:60) at org.jboss.netty.channel.SimpleChannelHandler.handleUpstream(SimpleChannelHandler.java:88) at org.jboss.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:564) at org.jboss.netty.channel.DefaultChannelPipeline$DefaultChannelHandlerContext.sendUpstream(DefaultChannelPipeline.java:791) at org.jboss.netty.handler.codec.http.HttpChunkAggregator.messageReceived(HttpChunkAggregator.java:145) at org.jboss.netty.channel.SimpleChannelUpstreamHandler.handleUpstream(SimpleChannelUpstreamHandler.java:70) at org.jboss.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:564) at org.jboss.netty.channel.DefaultChannelPipeline$DefaultChannelHandlerContext.sendUpstream(DefaultChannelPipeline.java:791) ``` at ..... ``` ---

> [@Kuckkuck](#): > > java.lang.ClassCastException: org.elasticsearch.action.admin.indices.stats.CommonStatsFlags cannot be cast to [Ljava.lang.String; Ah the error is inside of a plugin and is fixed in elasticsearch-readonlyrest-plugin 1.9.1. ---
