-----------------------------------------------
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
