jdbc - 无法配置 JDBC 输入

Question

以下是我的配置 -

input {
    jdbc {
           jdbc_driver_class => "org.apache.derby.jdbc.EmbeddedDriver"   
           jdbc_connection_string => "jdbc:derby://localhost:3306/test"
           jdbc_user => "root"
           jdbc_password => "password"
           statement => "select * from user"                    
         }
      }

filter {  
         #csv {
                #columns => ["cdatetime", "address", "district", "beat", "grid", "crimedescr", "ucr_ncic_code",
                #                                   "latitude","longitude"]          
                #separator => ","
             }
       #}

output { 
         elasticsearch { host => localhost protocol => http index => test user => pavan  password => password  } 
         stdout { codec => rubydebug } 
       }

当我运行配置文件时，我收到以下错误 -

The error reported is: 
  org.apache.derby.jdbc.EmbeddedDriver not loaded

谁能帮我解决它？我当前的 Java 版本是 -

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
