一、错误

Caused by: org.apache.flink.core.fs.UnsupportedFileSystemSchemeException: Could not find a file system implementation for scheme ‘hdfs’. The scheme is not directly supported by Flink and no Hadoop file system to support this scheme could be loaded.

二、现象

找不多hadoop相关的jar包

三、原因

我使用的hadoop的版本是2.8.5，flink的版本是1.9.0
因为flink的checkpoint是需要记录在hdfs上，但是应该是flink1.8之后的就把hadoop的一些依赖题除了，所以报错找不到相应的jar包。

四、解决方案

在flink的lib中手动导入：
flink-shaded-hadoop2-uber-2.8.3-1.8.2.jar
