我的火花流媒体工作（火花1.6.1，kafka 0.9.0）正在消耗Kafka Topic的20个分区。 oracle DB中保留了偏移量。
在作业启动时，我会从Oracle读取偏移量（读取一次），并在处理后将偏移量写入oracle。
我的工作成功运行了8小时，但由于以下原因失败了。失败期间kafka主题，spark程序，oracle代码没有变化。
有谁可以告诉我为什么我在正在运行的火花流工作中收到此错误？

对我来说，问题只是我的Kafka服务器被中断了。很容易启动它：
./bin/kafka-server-start.sh -daemon config/server.properties
