Subject [jira] Updated: (HADOOP-6194) Add service base class and tests to hadoop-common/util
Date Mon, 26 Apr 2010 20:56:33 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6194?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.
