Steve Loughran updated HADOOP-6194:
-----------------------------------
Attachment: HADOOP-6194.patch
This is the most recent version of the lifecycle/service base class for
hadoop-common
# Named {{HadoopService}} so that the Service in the security package doesn't
cause confusion
# the protected methods are {{serviceStart}} and {{serviceClose{{
# Anything purely of interest to those nodes that have workers is in the
abstract subclass {{HadoopServiceWithWorkers}}. Currently there's just one
abstract method to return the no of workers, though I'd like there to be a
standard way to get the list of workers and ports and last reported time,
which we could then feed to management tools and a standard servlet that would
report this up. That is future work, these base classes just set things up.
> Add service base class and tests to hadoop-common/util

> For a service base class, we need to add to common

> # A mock Service class (it's not in test, its in src/, because it helps in
> functional tests downstream)
> # Unit tests
> This is the issue to cover this work
