Oozie Fails - Running MRv1 on CDH 5.4.2

I'm trying to run an oozie workflow the should execute MRv1 hadoop job.

Started with Cloudera QuickStart VM 5.4.2-0. Configured it to use MRv1 (appended at the bottom).

But the workflow fails:

The strange thing is that when I look at the classpath, it is loading the jar files from the right location; namely /usr/lib/hadoop-0.20-mapreduce

-----configurations----

Configured OOzie to use MapReduce instead of yarn:
- Changed config for Oozie in CDH by changing: MapReduce Service from YARN to MapReduce
- Changed config for Oozie in by setting oozie-site.xml valve value:
  
  <property> <name>oozie.service.HadoopAccessorService.jobTracker.whitelist</name> <value>quickstart.cloudera:8021</value> </property>
- Changed tomcat config using alternatives: sudo alternatives --config oozie-tomcat-deployment -- chose tomcat-conf.http.mr1
Configured Hadoop to use MapReduce: sudo alternatives --config hadoop-conf -- chose conf.cloudera.mapreduce

Solution

I had forgotten to update the actions to use MR1:

$ sudo -u oozie hadoop fs -rmr /user/oozie/share

sudo oozie-setup sharelib create -fs <FS_URI> -locallib /usr/lib/oozie/oozie-sharelib-mr1
