下载安装包,并解压,不做任何配置,为local模式
执行example中的wordcount.jar 记得输入参数和输出参数
记得在flink目录下面输入命令,不然会报错,找不到配置文件

Please specify the directory containing the configuration file through the 'FLINK_CONF_DIR' environment variable. at org.apache.flink.client.cli.CliFrontend.getConfigurationDirectoryFromEnv(CliFrontend.java:1160) at org.apache.flink.client.cli.CliFrontend.main(CliFrontend.java:1109)
可以配置环境变量,记得配置flink配置文件的变量:FLINK_CONF_DIR
