I am trying to import some data which is currently sitting in a MySQL database to Cloudera Search (SolrCloud) but just cant get it to work.   Here's  my setup:   4 node cluster CDH 5.4.4 Solr installed and running fine - checked with the enron-email sample data   Step 1. Downloaded solrconfig files using the command: solrctl instancedir --generate $HOME/solr_configs2   Step 2. Modified solrconfig.xml to include the following lines: <lib dir="../../../contrib/dataimporthandler/lib/" regex=".*\.jar" /> <lib dir="../../../dist/" regex="solr-dataimporthandler-\d.*\.jar" />   <requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="config">data-config.xml</str> </lst> </requestHandler>   Step 3: Created a file data-config.xml with the following contents: <dataConfig> <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://<server_ip>/<dbname>" batchSize="-1" zeroDateTimeBehavior="convertToNull" user="<db_user_name>" password="<db_password>"/> <document name="article"> <entity name="id" query="SELECT ....   SQL quer here ...." >   <field column="id" name="id" /> <field column="article_id" name="article_id" /> ....   </entity> </document> </dataConfig>     Step 4 Created schema.xml to conform to the schema being returned by the MySQL query     Step 5 Uploaded config to SolrCloud using the command: solrctl instancedir --create impactprint $HOME/solr_configs2   Step 6  Tried creating the collection using the command : solrctl collection --create name_of_collection -s 2 -c name_of_collection     The above generates the following error : Error: A call to SolrCloud WEB APIs failed: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: application/xml;charset=UTF-8 Transfer-Encoding: chunked Date: Mon, 11 Jan 2016 10:57:04 GMT <?xml version="1.0" encoding="UTF-8"?> <response> <lst name="responseHeader"> <int name="status"> 0</int> <int name="QTime"> 3565</int> </lst> <lst name="failure"> <str> org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'impactprint_shard1_replica1': Unable to create core [impactprint_shard1_replica1] Caused by: org.apache.solr.handler.dataimport.DataImportHandler</str> <str> org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'impactprint_shard2_replica1': Unable to create core [impactprint_shard2_replica1] Caused by: org.apache.solr.handler.dataimport.DataImportHandler</str> </lst> </response>     Please help!   ...
