> I am starting to use the new Operator event subscription API to get notified
> of task changes. The initial TASK_STAGING event has a good amount of
> information, but unfortunately future events like TASK_RUNNING include almost
> no metadata. This means that any task information that cannot be determined
> until the task launches (in my particular case, the IP address assigned by
> the Docker containerizer) is not available through the event stream.
> Here is a gist of a single task that was launched, comparing the information
> in 'state.json' vs the subscribed events:
> https://gist.github.com/stevenschlansker/c1d32aa9ce37a73f9c4d64347397d3b8
> Note particularly how the IP address never shows in the event stream.
> Task updates should expose the task information that changed. If this is too
> onerous, maybe the subscription call can take optional sets of data to
> include, with the first one being additional task metadata.
> A possible workaround is to use the task events to fetch 'state.json'
> separately, but this is inherently racy and totally undermines the utility of
> the event stream api.
