Add standard interface/methods for all services to query IPC and HTTP addresses
and ports
-----------------------------------------------------------------------------------------
Key: HADOOP-4383
URL: https://issues.apache.org/jira/browse/HADOOP-4383
Project: Hadoop Core
Issue Type: Improvement
Components: dfs, mapred
Affects Versions: 0.20.0
Reporter: Steve Loughran
Priority: Minor
This is something I've ended up doing in subclasses of all the services:
methods to get at the IPC and HTTP port and addresses. Some services have
exported methods for this (JobTracker), others package-private member variables
(namenode), while others don't allow you to get at all the data (Datanode keeps
the http server private).
A uniform way to query any service for its live port and address values make
some aspects of service management much easier, such as feeding those values in
to http page monitoring tools.
