org.apache.hadoop.mapred.StatusHttpServer
Create a Jetty embedded server to answer http requests. The primary goal is to serve up status information for the server. There are three contexts: "/logs/" -> points to the log directory "/static/" -> points to common static files (src/webapps/static) "/" -> the jsp server code from (src/webapps/) @author Owen O'Malley
