Subject flink to HDFS Couldn't create proxy provider class ***.ha.ConfiguredFailoverProxyProvider
Date Thu, 29 Aug 2019 13:34:13 GMT


Dear All


【我想咨询一下flink消费数据入HDFS的一个问题】


1. 因为我们有多个HDFS集群
2. 我采用的是将hdfs-site.xml和core-site.xml放到resources文件下


【问题】

【尝试】
1. 载入hadoop-hdfs-*.jar文件
2. 载入flink-connector-filesystem-*.jar文件


还是同样的报错
