flink 集群 Standalone 模式 高可用部署无法启动已解决

hadoop , zookeeper,工作正常，flink-standalone 启动正常。在搭建HA集群时，集群启动未报错，查看jps时发现没有进程，查看日志出现如下内容：
具体报错信息

Shutting StandaloneSessionClusterEntrypoint down with application status FAILED. Diagnostics java.io.IOException: Could not create FileSystem for highly available storage path (hdfs://node7-1/flink/ha/flinkCluster)

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. For a full list of supported file systems, please see https://ci.apache.org/projects/flink/flink-docs-stable/ops/filesystems/.

Caused by: org.apache.flink.core.fs.UnsupportedFileSystemSchemeException: Hadoop is not in the classpath/dependencies.

问题解决

1. 缺少hadoop的jar包，可以去 官网下载 ，找到flink-1.7.2-bin-hadoop28-scala_2.12.tgz ，我用的是flink1.11.2的，里面没有hadoop的jar包，flink-1.7.2里面有，flink-1.7.2以后的版本都没有了，下载也能应用到flink-1.11.2。
   
2. 压缩包打开，找到目录flink-1.7.2-bin-hadoop28-scala_2.11.tar\flink-1.7.2\lib，找到flink-shaded-hadoop2-uber-1.7.2.jar，复制出来，上传到虚拟机中的flink-1.11.2的lib目录下，重新启动服务，集群启动起来
