Make StatusHttpServer (usefully) subclassable
---------------------------------------------
Key: HADOOP-2024
URL: https://issues.apache.org/jira/browse/HADOOP-2024
Project: Hadoop
Issue Type: Improvement
Components: mapred
Reporter: stack
Priority: Minor
hbase puts up webapps modelled on those deployed by dfs and mapreduce.
Currently it does this by copying the bulk of StatusHttpServer down to hbase
util as a new class named InfoServer. StatusHttpServer is copied rather than
subclassed because I need access to the currently-private resource loading.
As is, understandably, all webapp-related resources are presumed under the
first 'webapps' directory found. It doesn't allow for the new condition where
some resources can be found in hadoop and then others in hbase.
