kafka两阶段提交时候遇到这个错误，是因为kafka数据回滚元数据丢失导致的么？
错误信息如下：
This exception is raised by the broker if it could not locate the producer metadata associated with the producerId in question. This could happen if, for instance, the producer\'s records were deleted because their retention time had elapsed. Once the last records of the producerId are removed, the producer\'s metadata is removed from the broker, and future appends by the producer will return this exception.
报错异常栈如下
