The backport to 1.5.x breaks the build:

> Key: MESOS-8942
> URL: https://issues.apache.org/jira/browse/MESOS-8942
> Project: Mesos
> Issue Type: Task
> Components: HTTP API
> Affects Versions: 1.4.1, 1.5.0, 1.6.0
> Reporter: Alexander Rukletsov
> Assignee: Alexander Rukletsov
> Priority: Major
> Labels: api, mesosphere, streaming-api
> Fix For: 1.4.2, 1.5.2, 1.7.0, 1.6.1
>
>
> Currently, Master API subscribers get task status updates when task state
> changes (the actual logic is [slightly more
> complex|https://github.com/apache/mesos/blob/d7d7cfbc3e5609fc9a4e8de8203a6ecb11afeac7/src/master/master.cpp#L10794-L10841]).
> We use task status updates to deliver health and check information to
> schedulers, in which case task state does not change. Hence these updates are
> filtered out and the subscribers do not get any task health updates.
> Here is a test that confirms the described behaviour:
