flink消费不到kafka数据

1. flink消费不到kafka数据

2. 一个服务器上有kafka集群，一直在生产数据，消费数据的程序在另一个服务器，但是一直消费不到，两个服务器能ping通，用的flink消费，端口也能telnet通

3. 以下日志一直循环打印

   20/07/10 04:17:21 INFO checkpoint.CheckpointCoordinator: Completed checkpoint 20 for job a205b888f33a760b54917c4376f1fd74 (9087 bytes in 5 ms).
   20/07/10 04:17:21 WARN internal.Kafka09Fetcher: Committing offsets to Kafka takes longer than the checkpoint interval. Skipping commit of previous offsets because newer complete checkpoint offsets are available. This does not compromise Flink's checkpoint integrity.
