Apache kafka Kafka Spark Stream引发异常：没有分区的当前分配

下面是我创建spark kafka流的scala代码：

val kafkaParams = Map[String, Object](
"bootstrap.servers" -> "server110:2181,server110:9092",
"zookeeper" -> "server110:2181",
"key.deserializer" -> classOf[StringDeserializer],
"value.deserializer" -> classOf[StringDeserializer],
"group.id" -> "example",
"auto.offset.reset" -> "latest",
"enable.auto.commit" -> (false: java.lang.Boolean)
)
val topics = Array("ABTest")
val stream = KafkaUtils.createDirectStream[String, String](
ssc,
PreferConsistent,
Subscribe[String, String](topics, kafkaParams)
)

但在运行10小时后，它会抛出异常：

显然，分区ABTestMsg-0已经为此使用者撤销，但spark streaming使用者似乎没有意识到这一点，并继续使用此撤销主题分区的数据，因此发生异常，整个spark作业中止。

我认为kafka重新平衡事件是非常正常的，我如何修改我的代码以使Spark streaming正确处理分区撤销事件？

我花了一些时间才弄明白这一点。这是因为重新平衡。在我的例子中，我使用ZKClient org.I0Itec.ZKClient.ZKClient client=new ZKClient（“servername:2181”）List topicsList=JavaConversions.asJavaList（ZkUtils.getAllTopics（client））获取主题及其分区；ThanksAssign需要主题的偏移值。当使用Assign[String，String]（主题，kafkaParams）代替Subscribe[String，String]（主题，kafkaParams）时，它抛出编译错误，表示没有重载的方法可以找到很好的答案。非常感谢。
