Spark版本不兼容导致Standalone集群无法连接问题
一、Spark版本不一致报错现象
当使用client模式连接Spark的standalone集群时，报错所有的spark master的节点都没有回应。
二、问题排查思路
通过client端的日志产看没有什么有价值的信息，需要看下spark端的master的日志，docker logs spark-master 产看docker容器spark-master的日志如下：

24/01/09 09:29:46 INFO Master: 97f5a5d12509:38871 got disassociated, removing it.
三、错误分析
通过上面master的报错日志，可以看到client（172.225.222.2）已经连接到master（172.225.222.3和）的两个节点了，只不过后面master发现客户端脱离关联，又把他移除了。说明client连接master之间的通信是没问题的。那么问题应该是出现在master反向连接client的出了问题。
3.1 使用nc命令模拟端口占用，使用master反向连接client
因为client与master连接不久就断开了，程序无法长时间占用一个端口，因此，使用nc模拟一个应用程序占用一个随机端口。在master所在的容器使用telnet ip 端口方式与client通信。
1、进入到容器
docker exec -it spark-master bash
2、使用nc占用随机端口
nc -lk 30000
监听的端口与实际设置的不一致，端口出现了转移？导致master连接client时上报的端口和使用的端口不一致？
3、排查端口不一致原因
经过排查，发现不同的docker版本，镜像lidaxi2019/webecho:0.1是好的，镜像ubuntu:18.04是会转移端口的，其中的nc的lib库和版本都不一样，本人所使用docker版本的nc如果要绑定一个特定端口需要使用的命令为：
nc -lk -p 30000
不然，就会出现如下差异，缺少了bind这个system call。当使用-p命令后，端口绑定正常了，排除端口转移的问题。
4、在看序列化错误
24/01/09 09:29:26 ERROR TransportRequestHandler: Error while invoking RpcHandler#receive() for one-way message.
java.io.InvalidClassException: org.apache.spark.deploy.ApplicationDescription; local class incompatible: stream classdesc serialVersionUID = 1574364215946805297, local class serialVersionUID = -6826680068825109317
如下博客帮了很大忙，提示为因为client和master的spark的版本不同，导致client端编译的uid跟master端类的序列化id不一致。
https://blog.csdn.net/u013124704/article/details/51437468
5、查看版本差异
进入到client和master的容器的spark的bin目录，使用sh spark-shell ，发现二者版本果然不一致，将client的版本也改为3.4.1之后，问题解决。spark小版本都有这么大差异，只能说spark变得对开发者越来越不友好了。
