Passing parameters to MapReduce through Oozie
Hello,
I am trying to pass parameters to my MapReduce job from Oozie MapReduce
action. Here's how I'm declaring the parameters in Oozie workflow.xml:
<property>
<name>param1</name>
<value>paramValue</value>
</property>
However, I'm not sure if this is the right way. Even if it is, I don't know
how to access those parameters from within my Map-Reduce job.
I tried
configuration.get("param1");
but, it doesn't work.
I would really appreciate some advise on this.
Thank you!
Regards,
Shailesh

If you use mapreduce-action, then is the configuration lookup done
within a Mapper/Reducer? If so, how are you grabbing the configuration
object? Via the overridden "configure(JobConf conf)" method?
