in multiprocessing pool map how to stop one process from executing ahead

2018-03-20 Thread Subramanian P V
I am excecting custom commands like shell  on multiple linux hosts.  and if in 
one host one of the commands fail. I want that process not to proceed. If the 
remote command throws an error i am logging it .. but the process goes to next 
command . but if i terminate the command, the process will terminate all other 
processes on other linux machines as well.
