解决办法：
下载flink-shaded-hadoop-2-uber-2.7.5-10.0.jar 或 maven：
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-shaded-hadoop-2-uber</artifactId>
<version>2.7.5-10.0</version>
</dependency>
然后将flink-shaded-hadoop-2-uber-2.7.5-10.0.jar放在flink的lib目录下
cp \
/home/hadoop/maven_repository/org/apache/flink/flink-shaded-hadoop-2-uber/2.7.5-10.0/flink-shaded-hadoop-2-uber-2.7.5-10.0.jar \
/usr/local/flink/lib
运行成功：
