SparkSubmit进程无法强制kill掉
0. 写在前面
- 操作系统：Linux（CentOS7.5）
- Spark版本：Spark3.0.0
- Scala版本：Scala2.12.1
本文出现「SparkSubmit进程无法强制kill掉」这种情况是在使用Spark-Shell环境下执行MLib的相关程序后导致的
1. 正文
注意：SparkSubmit进程无法强制kill掉，即使是
kill -9多次不成功！！
- 新会话窗口执行kill强制命令
尝试新开一个会话窗口，在新的会话窗口强制进行
kill，依旧是不能强制杀掉这个SparkSubmit进程
- 查看SparkSubmit对应进程号的父进程是否存在，如果存在，直接杀掉其对应的父进程。
该方法查询不到对应的父进程，请换用下方的另一种方法
查看这个SparkSubmit进程的父进程有哪些，命令如下方图所示：
查询到的完整信息如下代码块所示：

- 解释说明：
- Pid: 2116 --> 表示当前进程
- PPid: 2105 --> 表示当前进程对应的父进程
- 获取到SparkSubmit进程对应的父进程号后，首先强制杀掉父进程，再次查看进程是否kill成功，命令如下方所示
kill -9 sub_pid
可以看到我们以及成功kill掉了SparkSubmit进程了
- 重新回到旧的会话窗口，可以观察到如下图所示的进程情况：
2. Flink配合Kafka使用问题的记录
Flink通过Kafka读取数据进行分组统计求最大值，并设置了窗口的大小，将Kafka生产端Input主题的数据消费到Output主题中

出现错误的原因是：Kafka库与Flink的反向类加载方法不兼容，修改 Flink安装目录下的
conf/flink-conf.yaml并重新启动Flinkclassloader.resolve-order: parent-first
注意，在Flink中执行
bin/flink run --class class_refrence your.jar命令前要将Jar包所需要的依赖放进到 Flink安装目录下的lib目录中。
全文结束！！！
