[jira] [Created] (OOZIE-1063) Provide documentation on configuring
Oozie to use new Hadoop API
Michael Katzenellenbogen created OOZIE-1063:
-----------------------------------------------
Summary: Provide documentation on configuring Oozie to use new Hadoop API
Key: OOZIE-1063
URL: https://issues.apache.org/jira/browse/OOZIE-1063
Project: Oozie
Issue Type: Improvement
Components: docs
Reporter: Michael Katzenellenbogen
To use the newer mapreduce.* Hadoop API, the Oozie workflow XML configuration should have the mapred.mapper|reducer.new-api property set to true. This is currently undocumented (on the Oozie side), and throws mysterious RuntimeExceptions when using the newer API.
Example RuntimeExceptions:
java.lang.RuntimeException: class com.foo.bar.SomeMapper not org.apache.hadoop.mapred.Mapper
java.lang.RuntimeException: class com.foo.bar.SomeOutputFormat not org.apache.hadoop.mapred.OutputFormat

Some comments are there in old github wiki:
https://github.com/yahoo/oozie/wiki/Oozie-WF-use-cases
Looks for "How to run Map-reduce job written using new Hadoop API?"
We might need to integrate this into latest doc.

Err, yeah, this was in reference to adding/integrating into the release documentation. Should've been more specific about that.
