Description

While processing requests to /state, the Mesos agent calls Framework::allocatedResources(), which in turn calls Slave::getExecutorInfo() on executors associated with the framework's pending tasks.

In the case of tasks launched as part of task groups, this leads to the failure of the assertion here. This means that the check will fail if the agent processes a request to /state at a time when it has pending tasks launched as part of a task group.

This assertion should be removed since this helper function is now used with task groups.
