stack updated HADOOP-3824:
--------------------------
Attachment: 3824_20080724-v2.patch
Would you consider using this version of your patch?
Only change is to the HttpServer constructor calling out to a new method named
addWebapps. Its in this method that we add webapps and servlets rather than up
in the constructor. Makes it so a subclass can influence whats loaded (not
load some or load with different names, etc.).
Use case is something like hbase. Currently we have a duplicate of the old
StatusHttpServer. We call it InfoServer down in hbase-land. Hbase has webapps
like those in hadoop-core only they want just some of the webapps+servlets that
hadoop-core used put up in InfoServer. We made the duplicate because we
couldn't subclass old StatusHttpServer (HADOOP-2024 was attempt at getting in a
patch that would make it subclassable).
Thanks for your consideration. THanks.
