Hi, Regarding the issue, I have tried to put the following in zoo.cfg under ZooKeeper: 4lw.commands.whitelist=mntr,conf,ruok
But it is still showing this error. *"Errors: - membership: Check 4lq.commands.whitelist setting in zookeeper configuration file."* As I am using SolrCloud, the collection config can still be loaded to ZooKeeper as per normal. But if I tried to create a collection, I will get the following error: { "responseHeader":{ "status":400, "QTime":686}, "failure":{ "192.168.1.2:8983_solr":"org.apache.solr.client.solrj.SolrServerException:IOException occurred when talking to server at:http://192.168.1.2:8983/solr", "192.168.1.2:8984_solr":"org.apache.solr.client.solrj.SolrServerException:IOException occurred when talking to server at:http://192.168.1.2:8984/solr"}, "Operation create caused exception:":"org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Underlying core creation failed while creating collection: collection1", "exception":{f "msg":"Underlying core creation failed while creating collection: collection1", "rspCode":400}, "error":{ "metadata":[ "error-class","org.apache.solr.common.SolrException", "root-error-class","org.apache.solr.common.SolrException"], "msg":"Underlying core creation failed while creating collection: collection1", "code":400}} Is there anything which I may have missed out?
