Custom Partitioner not working in Oozie Mapreduce action

Question

I have implemented secondary sort in mapreduce and trying to execute it using Oozie (From Hue).

Though I have set the partitioner class in the properties, the partitioner is not being executed. So, I'm not getting output as expected.

The same code runs fine when run using hadoop command.

And here is my workflow.xml

<workflow-app name="MyTriplets" xmlns="uri:oozie:workflow:0.5">
<start to="mapreduce-598d"/>
<kill name="Kill">
    <message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<action name="mapreduce-598d">
    <map-reduce>
        <job-tracker>${jobTracker}</job-tracker>
        <name-node>${nameNode}</name-node>

        </configuration>
    </map-reduce>
    <ok to="End"/>
    <error to="Kill"/>
</action>
<end name="End"/>

When running using hadoop jar command, I set the partitioner class using JobConf.setPartitionerClass API.

Not sure why my partitioner is not executed when running using Oozie. Inspite of adding

            <property>
                <name>mapred.partitioner.class</name>
                <value>PonRankPartitioner</value>
            </property>

Any What I'm missing when running it from Oozie ??

Answer 1

Solved this by re-writing the mapreduce job using new API's.

The property used in oozie workflow for partitioner was mapreduce.partitioner.class.
