配置信息： high-availability: zookeeper
high-availability.storageDir: hdfs:///flink/ha/

high-availability.zookeeper.path.root: /flink
- 启动方式与配置
当high-availability: zookeeper，选择使用flink run -m的方式提交job时，-m option会被忽略掉（参考flink client源码），导致提交job失败。会出现如下错误信息：

因为flink高可用需要用zookeeper进行jm的leader选举，所以是必须配置的。
解决办法：修改提交方式为flink run -yid appid my.jar的方式就可以正常提交了。通过指定appid，可以将Job提交到对应的yarn cluster上。
- 使用flink run -yid appid my.jar的问题

原因：使用这种方式提交job时会用到flink-shaded-hadoop2-uber-1.7.2.jar .在flink的源码中可以看到，此包的pom中把相关的jersey全部都exclude掉了，导致缺包。
解决办法： 将对应版本的jersey.core的jar放到$FLINK_HOME/lib下
- 其他可能遇到的问题
hdfs目录权限的问题。
原因：flink需要将高可用相关信息写入到配置的hdfs目录下，如果没有写权限，也会出现提交失败的问题。
