I'm trying to do a simple job using oozie.
It will be a one simple Pig Action.
I have a file : FirstScript.pig containing:
dual = LOAD 'default.dual' USING org.apache.hcatalog.pig.HCatLoader();
store dual into 'dummy_file.txt' using PigStorage();
and a workflow.xml containing:
<workflow-app name="FirstWorkFlow" xmlns="uri:oozie:workflow:0.2">
<start to="FirstJob"/>
<action name="FirstJob">
<pig>
<job-tracker>hadoop:50300</job-tracker>
<name-node>hdfs://hadoop:8020</name-node>
<script>/FirstScript.pig</script>
</pig>
<ok to="okjob"/>
<error to="errorjob"/>
</action>
<ok name='okjob'>
<message>job OK, message[${wf:errorMessage()}]</message>
</ok>
<error name='errorjob'>
<message>job error, error message[${wf:errorMessage()}]</message>
</error>
</workflow-app>
I have created structure :
FirstScript
|- lib
|---FirstScript.pig
|- workflow.xml
And what now?
How do I deploy it and run with oozie?
Can anyone more experienced help?
Regards
Pawel
I do it like this:
hadoop fs -put workflow.xml some_dir/
oozie job --oozie http://your_host:11000/oozie -config cluster_conf.xml -run
and my cluster_conf.xml looks like this (please check your ports first they depend on Hadoop distro):
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
