already being killed.

Yes, that was the intent, but you right, it is inconsistent to what we do. Will 
drop these lines in favor of longer description above.

Thanks! I'll drop this since I'll remove these lines altogether as per comment 
above.

Good point, will adjust the comment.

Fix it, then Ship it!





CHANGELOG (line 16)


The task kill policy defined within TaskInfo can now be overridden when the 
scheduler kills the task. This can be used by schedulers to forcefully kill a 
task which is already being killed, e.g. if something went wrong during a 
graceful kill and a forcible kill is desired. Note that it is the executor's 
responsibility to honor the 'Event.kill.kill_policy' field and override the 
task's kill policy. To use this feature, schedulers and executors must support 
HTTP API; use the `--http_command_executor` agent flag to ensure the agent 
launches the HTTP API based command executor.



CHANGELOG (line 48)


whoops? please commit this separately. But notice that there are a number 
of inconsistent past vs. present tense wording in the CHANGELOG, poor grammar, 
etc. I'd rather see a sweep on a section (e.g. 0.29.0) to minimize history 
churn.



CHANGELOG (lines 61 - 63)


I was initially surprised to see MESOS-4908 repeated here, but I suppose 
the intent was to list all non-deprecation API changes here? If so, we're not 
doing that already (e.g. MESOS-4909 and MESOS-4949 in 0.29.0 for example).

It seems the current approach is that 'new features' may include some API 
changes, but these aren't repeated in 'Additional API' changes. While it would 
be great to have a clearer approach, can you follow the existing approach?



CHANGELOG (line 62)


no need for the "'s" here:

s/scheduler's/scheduler/
s/executor's/executor/



include/mesos/executor/executor.proto (lines 90 - 91)


All of the .proto comments introduced here would benefit from also 
mentioning that the kill policy overrides any previously specified 
kill.kill_policy. Currently it only seems clear that the kill.kill_policy 
overrides task_info.kill_policy. 

Perhaps for now, we just explicitly state that the grace period may be 
"overridden" (or "adjusted"?) in order to give more or less time to a graceful 
kill that is in progress.
