File input/clicks.csv does not exist or the user running Flink ('Administrator') has insufficient permissions to access it.

解决办法：
实际上是文件不存在，路径写错

因此需要把所读取的本地文件发送到每台taskmanage机器和jobmanage机器中，否则会报错FileNotFoundException和IOException，
比如 does not exist or the user running Flink ('root') has insufficient permissions to access it

运行flink程序前准备数据，flink程序所读取的本地文件必须放到每台taskmanage机器和jobmanage机器中
