Flink报错：SplitFetcher thread 0 received unexpected exception while polling the records

Flink报错：SplitFetcher thread 0 received unexpected exception while polling the records

运行Flink代码时出现报错信息，仔细分析报错主要有以下几点：

Caused by: org.apache.flink.runtime.JobException: Recovery is suppressed by NoRestartBackoffTimeStrategy

Caused by: java.lang.RuntimeException: One or more fetchers have encountered exception

Caused by: java.lang.RuntimeException: SplitFetcher thread 0 received unexpected exception while polling the records

Timeout of 60000ms expired before the position for partition tms_ods_0-0 could be determined

报错详细内容如下：

排查了半天，有些说是没有设置table.exec.hive.fallback-mapred-reader: true，有些说是重新创建一个topic，还有些说是需要修改配置文件。

这一问题不同的人遇到可能解决的方案会有所不同，我是因为Kafka集群没有完全启动，只有一个节点启动成功了。结果一直报告该错误，花了相当长时间排查。
