[jira] [Comment Edited] (AURORA-1572) SIGTERM is not sent to child processes

    [ https://issues.apache.org/jira/browse/AURORA-1572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15086255#comment-15086255 ]

-------------------------------------------------------------

Basically, I have several bash commands being executed in an aurora process, i.e.

cmd = " <cmd 0> && <cmd 1> && ... <cmd n>"

In the case above, only "cmd 0" seems to receive the sigterm.

There are many workarounds for this... 
One solution would be to simply designate a separate aurora process for each cmd. Yet, each command is tightly coupled to each other and it would be nice to have then all run together as a single aurora process. etc...

> In terminate_process, SIGTERM is sent to the parent process only. This seems like a deliberate design choice given that the kill_process does send a SIGKILL to each child process. Is there a reason why SIGTERM is not also sent the to child processes? 
> For reference, I'm referring to the functions defined in the thermos helper.py file.
