所有，我使用Kafka1.0.0镜头Cassandra源连接器。我已经完成了快速入门中提到的所有设置。它也在运行。但问题是，一旦我在配置文件中提供初始偏移量，我的连接器就无法获取数据。在我的控制台上

INFO message for query : "SELECT account_sid,datetime,price,request,response FROM testdb.testtable WHERE datetime > maxTimeuuid(?) AND datetime <= minTimeuuid(?) ALLOW FILTERING executing with bindings (2018-01-01T08:00:00Z, 2018-01-01T11:07:54Z)"

在casandra表上分别执行这个查询时，我得到的是结果。请说明哪里出了问题。提前谢谢你的帮助。
下面是配置文件：

{  
  "name":"cassandra-source",
  "config":{  
    "tasks.max":"1",
    "connector.class":"com.datamountaineer.streamreactor.connect.cassandra.source.CassandraSourceConnector",
    "connect.cassandra.contact.points":"abc.test.com",
    "connect.cassandra.port":9042,
    "connect.cassandra.username":"user",
    "connect.cassandra.password":"password",
    "connect.cassandra.key.space":"testdb",
    "connect.cassandra.initial.offset":"2018-01-01 00:00:00.0000000Z",
    "connect.cassandra.kcql":"INSERT INTO testtable SELECT account_sid,datetime,price,request,response FROM carrier_lookup_list PK datetime INCREMENTALMODE=TIMEUUID",
    "connect.progress.enabled":true
  }
}
