Many thanks. Both suggestions worked well.
<ip-address>:port/conf - displayed all of the conf Running $hadoop getcong -confKey <property> would tell me if changed property was picked up by the system. Thanks! p.s. where is the below property set, in the mapred-site.xml on the JT? I currently have it as: <name>mapred.task.tracker.report.address</name> <value>127.0.0.1:0</value> and wondering whether it is responsible for some of my broken webUI links.

Mostly, the division is between clients and servers. Which one were you asking for? Higher versions of Hadoop have, for HDFS alone, a getconf method: $ hdfs getconf <KEY> All versions of Hadoop let you load and dump a Configuration object XML, which is helpful in seeing what form of core-site.xml values has it loaded from the classpath (or not): $ hadoop org.apache.hadoop.conf.Configuration Almost all versions of hadoop let you visit a daemon's loaded config page, that represents the config object the daemon is running with, currently: Visit http://DAEMONHOST:PORT/conf (http://namenode:50070/conf for example at the NN) For job set information, the info Serge has passed earlier here is correct.
