How to kill a process which is running form a directory in CentOS?
问题
我们有一个要求，我们有同一个 Spark 应用程序（基本上是一个 .jar 文件）的副本，从不同的文件夹运行。我正在寻找一个使用 shell 命令的方法，可以在不终止其他 Spark 作业的情况下终止在一个文件夹中运行的 Spark 应用程序。
例如：
/home/user/Folder1 - CapStoneSpark.jar /home/user/Folder2 - CapStoneSpark.jar /home/user/Folder3 - CapStoneSpark.jar
在 jar 文件中的主类是 "CapStoneSparkMain"。假设，我想要终止仅在 Folder2 中运行的 CapStoneSpark.jar，而不影响或终止从 Folder1 和 Folder3 运行的 CapStoneSpark.jar，我应该怎么做？
我已经尝试过：
kill $(ps aux | grep 'CapStoneSparkMain' | awk '{print $2}')
但是，这会终止所有具有 "CapStoneSparkMain" 类的进程。
我只想终止从单个目录启动的进程，并且不想触及从其他目录运行的进程的副本。
英文:
We have a requirement where we have copies of the same Spark application (basically a .jar file) running from different folders. I am looking for a shell command using which I can kill the Spark app running in one folder without killing other spark jobs.
Ex:
> /home/user/Folder1 - CapStoneSpark.jar
> /home/user/Folder2 - CapStoneSpark.jar
> /home/user/Folder3 - CapStoneSpark.jar
The main class in the jar file is "CapStoneSparkMain". Suppose, I want to kill the CapStoneSpark.jar running in Folder2 only without touching or killing the CapStoneSpark.jar running from Folder1 and Folder3, then what should I do?
I have already tried:
kill $(ps aux | grep 'CapStoneSparkMain' | awk '{print $2}')
But, it kills all the process which have "CapStoneSparkMain" class in them.
I only want to kill the process originating from a single directory and don't want to touch the copies of the processes running from other directories.

可以找到正在使用这些文件夹的所有进程ID：
lsof | grep /home/user/Folder | awk '{print "kill " $2}';
然后执行它：
lsof | grep /home/user/Folder | awk '{print "kill " $2}' | sh
英文:
You can find all Proccess ID's which using these folders:
lsof | grep /home/user/Folder | awk '{print "kill " $2}'
And execute it:
lsof | grep /home/user/Folder | awk '{print "kill " $2}'|sh

以下是翻译好的部分：
不清楚作业是如何启动的，但假设每个作业都在不同的工作目录中启动，那么有可能终止特定的作业。考虑到可以通过/proc/$$/cwd（指向作业文件夹的符号链接）找到每个进程的工作目录。基于上面建议的命令/循环：
kill_folder=/home/user/Folder2
for pp in $(ps aux | grep 'CapStoneSparkMain' | awk '{print $2}') ; do
if [[ /proc/$$/cwd -ef "$kill_folder" ]] && kill $$
done
该代码将检查符号链接/proc/$$/cwd是否与命名文件夹（kill_folder）匹配，并且只会对位于该文件夹中的进程发出终止命令。
英文:
It's not clear how the jobs are started, but assuming that each job is started with a different working direectory, it is possible kill the specific job. Given that it's possible to find the working directory of each process via the /proc/$$/cwd (symlink to the job folder). Building on the commands/loop suggested above:
kill_folder=/home/user/Folder2
for pp in $(ps aux | grep 'CapStoneSparkMain' | awk '{print $2}') ; do
if [[ /proc/$$/cwd -ef "$kill_folder" ]] && kill $$
done
The code will check if the symlink /proc/$$/cwd matches the named folder (kill_folder), and will only issue the kill to processes in that folder.

你好
一个用于检查用户的 for 循环...
for i in $(pidof application); do grep -o ${user} /proc/${i}/cmdline; done
并且如果符合你的要求，就在循环中对 ${i} 执行 kill 命令。
英文:
Hello
A for loop that check for the user in...
for i in $(pidof application); do grep -o ${user} /proc/${i}/cmdline; done
And if it fits your desire then put kill command on ${i} in loop.
