Review Comment:
yes, i mean, i did test for get host address from task-executor, when
reporter handle the failed or other final events, the task-executor is already
removed from repository.
assembly the host to channel is not ok, channel will removed when current
events are all reported, at this moment reassign host will not work, this is a
lifecycle overlapping issue, Channel or task-executor must have one to cover
the task's all lifecycle to hold the host.
