Window10安装Flink1.10.0-大坑

Window10安装Flink1.10.0

基本可以确定在window10安装Flink1.10.0启动时会出问题，特别恶心，目前无法修复，现在讲一讲我的踩坑经历。

首先我们去官网下载压缩包，官网下载地址：https://flink.apache.org/downloads.html

一步到位地址：http://archive.apache.org/dist/flink/flink-1.10.0/

下载后到本地解压到自己喜欢的一个路径下，尽量不要带中文路径，保持良好的开发规范。

找到对应安装路径下 apache-flink-1.10.0\bin找到 start-cluster.bat双击或者在cmd命令行执行。

正常是会非常顺利的起来，但是如果执行后会默认打开两个cmd窗口，一个是Jobmanager,一个是taskmanager，过了没一会，taskmanager的窗口突然就消失了，访问集群页面 http://localhost:8081/#/overview

发现taskmanager没有起来，此时此刻只能去 apache-flink-1.10.0\deps\log路径下去找taskmanager日志文件，查看到底是什么情况，我们会发现有一个 flink-用户名-taskmanager.log文件我们打开文件会提示类似错误

大致意思是说 taskmanager.cpu.cores 没有设置这个必需具体的参数，默认是NULL，需要我们手动设置一下具体的值，根据机器配置可自行设置参数，接下来重新集群还会提示很多类似的配置参数没设置的错误，而且每次只会提示一条，笔者在这里把所有的坑都踩了一下，最后的问题基本是window系统与Flink1.10.0不太兼容，建议换成Linux或者MAC环境。
