Flink kafka 不能正常消费

Flink 版本 1.6.3
kafka 版本 0.10

2019-07-18 10:13:51,908 WARN  org.apache.flink.streaming.connectors.kafka.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.

kafka 原来安装过，后卸载后再运行就出现此问题，flink输出该警告后不能消费数据
