[jira] [Created] (HADOOP-7702) Show the default configuration value
in /conf servlet as well
Show the default configuration value in /conf servlet as well
-------------------------------------------------------------
Key: HADOOP-7702
URL: https://issues.apache.org/jira/browse/HADOOP-7702
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 0.21.1
Reporter: Liyin Tang
HADOOP-6408 has shown all the configuration values in the configuration file in /conf servlet.
But some of the configuration value do not exist in config file but be set in the code as default value.
It would be nice to show all these default configuration values in the servlet as well.

----------------------------------------
I don't think this should be in conf, but it may need to be accessible somehow. Why? Because if I bring up a NN listening on 0.0.0.0 I'd like to know that fact, though I'd also like to know the live hostname ended up 10.4.1.1, and the live URL being hdfs://cluster1/
I've served up configs with these values and the prefix live. which aided management; I could imagine serving up a conf file under a different path that served up the live values with the names people expect -this could then be downloaded and used directly by a client program (which is what I effectively did)

@tang .. default values ....
A little confused by the term default values. Do you mean the undocumented config variables?

@Sanjay, it means undocumented conf variables which is only set in the source code.
