Java Code to Kill Process in Linux (VM in Azure cloud)

Step 1 : It uses JSch jar file. Make sure you have downloaded it.

Step 2 : Generate Private key for your linux machine in case you don't have. You can follow this link, for the same .

Step 3 : Copy the code below, modify the lines highlighted in yellow.
Step 4 : Create the main() method to call the below function.


public boolean killPythonProcess(){

        int count = 5;
     
        JSch jsch = new JSch();
        String prvkey = "E:\\myPrivateKey_rsa";
        String host = "bdp-hdp.cloudapp.net";
        String user = "lokesh";
        String command = "kill -9 `ps -ef | grep python | grep root | awk '{print $2}'`";
        try{
        jsch.addIdentity(prvkey);
        Session session = jsch.getSession(user, host, 22);
        session.setConfig("StrictHostKeyChecking", "no");
        session.connect();
        com.jcraft.jsch.Channel channel = session.openChannel("exec");
        ((ChannelExec) channel).setCommand(command);
        channel.setInputStream(null);
        channel.setOutputStream(System.out);
        ((ChannelExec) channel).setErrStream(System.err);
        InputStream in = channel.getInputStream();
        InputStream error = channel.getExtInputStream();
        channel.connect();
        byte[] tmp = new byte[1024];
        while (count >= 0) {
        while(error.available() > 0){
                     int i = error.read(tmp, 0, 1024);
                     if (i < 0)
                      break;
                     System.out.print(new String(tmp, 0, i));
               }
               while (in.available() > 0) {
                     int i = in.read(tmp, 0, 1024);
                     if (i < 0)
                            break;
                     System.out.print(new String(tmp, 0, i));
                }
               if (channel.isClosed()) {
                    System.out.println("exit-status: " + channel.getExitStatus());
                     break;
               }
               Thread.sleep(1000);
               count--;
        }
         channel.disconnect();
         session.disconnect();

        }
         catch(JSchException | InterruptedException |IOException j){
        return false;
           }

return true;
}


Step 5 : Bingo ! Done.
