load properties from property file into Configuration object
Hi,
I am trying to simplify code that loads properties from a property file
into a Configuration object:
Short excerpt of the code:
String configFile = args[0];
Properties p = new Properties();
p.load(new FileInputStream(configFile));
Configuration conf = getConf();
for (String prop: p.stringPropertyNames()) {
conf.set(prop, p.getProperty(prop));
}
The context is that my program can be run with an optional argument which
is a config file as "hadoop jar MYJAR MYCLASS -D property1=PROPERTY1 -D
property2=PROPERTY2 [MYCONFIGFILE]"
The format of MYCONFIGFILE is
"property3=PROPERTY3<NEWLINE>property4=PROPERTY4 etc."
Looking at the Configuration api, I didn't see any method that directly
loads properties from a property file.
Looking at the Configuration code, Configuration looks like a wrapper
around Properties, so I thought there was a similar method to
Properties.load or a method that sets several properties at the same time.
Is there a way to do this ?
Thanks very much,
Juan

I guess -conf won't support a config file in property format rather than
xml format ?

Re: load properties from property file into Configuration object

Yes, you could use an XML file for that purpose (i.e. lots of config
options) and pass it along with -conf.

Re: load properties from property file into Configuration object
Posted by Juan Pino <ju...@gmail.com>.
Thanks Harsh for your reply.
Yes I think I am using the Tool framework ("public class HadoopJob extends
Configured implements Tool" + main function is "System.exit(ToolRunner.run(new
HadoopJob(), args));")
"then you can pass -Dkey=val props directly into a config object at runtime"
I'm a bit confused by this: I can pass -D key1=val1 -D key2=val2 etc. on
the command line, and with the Tool framework, those properties get
automatically loaded in the Configuration object, but if I have many of
these properties, how can I write them into a config file so that these
properties are loaded into the Configuration object ?
Thanks very much,
Juan

This is a bit unnecessary to manually do. If you use the Tool
framework, then you can pass -Dkey=val props directly into a config
object at runtime. See
