Definitely unfortunate, but I
It sounds like using a multi_hashmap for now allows you to clean up the
code and avoid some bugs, without changing the existing behavior.
I agree that we would want a deprecation period if we changed the behavior.
It would also be unfortunate if we said we were dis-allowing duplicate task
ids but
Hi Joris,
Fair point: I didn't deliberately set out to change the behavior for
duplicate task IDs. Rather, it was a consequence of switching from
boost::circular_buffer to using a hashmap for managing completed
tasks. Using a hashmap has a few minor advantages [1], but we can

Hey Neil,
I concur that using duplicate task IDs is bad practice and asking for
trouble.
Could you please clarify *why* you want to use a hashmap? Is your goal to
remove duplicate task IDs or is this just a side-effect and you have a
different reason (e.g. performance) for using a hashmap?

Folks,
The master stores a cache of metadata about recently completed tasks;
for example, this information can be accessed via the "/tasks" HTTP
endpoint or the "GET_TASKS" call in the new Operator API.
The master currently stores this metadata using a list; this means
