Wso2 Siddhi事件表不能正确使用Apache storm

我尝试在执行计划中使用事件表，并尝试在Apache Storm的分布式模式下，将WSO2 CEP v4.1.0中的表与输入流连接起来

这是我的Siddhi查询

@Plan:name('ExecutionPlan')

@Import('InputStream:1.0.0')
define stream InputStream (id string, param1 int, param2 double, param3 string, param4 string, param5 string, param6 string, param7 string);

@Export('outputStream:1.0.0')
define stream OutputStream (id string, param3 string);

@From(eventtable = 'rdbms' , datasource.name = 'MYSQL' , table.name = 'cep') 
define table cepTable (id string, param1 int, param2 double, param3 string, param4 string, param5 string, param6 string, param7 string);

@name('query1') 
@dist(parallel='2', execGroup='Filtering')
partition with ( id of InputStream )
begin
  from InputStream join cepTable 
  on cepTable.id == InputStream.id 
  select InputStream.id as id, InputStream.param3 as param3  
  insert into OutputStream;
end;

但它提供了以下例外情况
