Oozie Hive Action Class Not Found Exception

Contributor

Trying to run a basic oozie workflow that completes a hive action and i keep getting this error: java.lang.ClassNotFoundException: Class org.apache.oozie.action.hadoop.HiveMain not found

Here is the XML workflow:

<workflow-app xmlns = "uri:oozie:workflow:0.5" name = "test_workflow">

<start to = "test_query" />

<!--Step 1 --> <action name = "test_query">

<hive xmlns = "uri:oozie:hive-action:0.5">

<job-tracker>jobtracker</job-tracker>

<name-node>nameNode</name-node>

<configuration> <property> <name>oozie.use.system.libpath</name> <value>true</value> </property>

<property> <name>oozie.libpath</name> <value>nameNode/user/oozie/share/lib/lib_20161215134654</value> </property> </configuration>

<script>hdfspath/hive.hql</script>

</hive>

<ok to = "end" />

<error to = "kill_job" />

</action>

<kill name = "kill_job"> <message>Job Failed</message> </kill>

<end name = "end" />

</workflow-app>

When i run this i get:

[Available ShareLib]

hive

distcp

Looks like some jar missing from classpath. Just realized this is more related to Oozie than Hive. Sorry I don't have more insights here. This might help:

Sometimes it happens when Oozie is having trouble referencing the proper oozie-sharelib-hive-<HDP Version>.jar

You should try to regenerate the oozie sharelib

1. Get a listing of hive sharelib content:

# oozie admin -oozie http://${OOZIE_HOST}:11000/oozie -shareliblist hive* > /tmp/hive_shareliblist_OLD.txt 2>&1

2. Now we will recreate the sharelib

# /usr/hdp/<HDP Version>/oozie/bin/oozie-setup.sh sharelib create -fs hdfs://${NAMENODE}

3. Again list the hive sharelib contents now.

# oozie admin -oozie http://${OOZIE_HOST}:11000/oozie -shareliblist hive* > /tmp/hive_shareliblist_NEW.txt 2>&1

4. For double verification list all hive sharelib directories in HDFS

# hdfs dfs -ls -R /user/oozie/share/lib/*/hive/* > /tmp/hive_libs_on_hdfs.txt 2>&1

5. Edit the "workflow.xml" and remove the line:

<property> 
     <name>oozie.libpath</name> 
     <value>${nameNodeHost:8020}/user/oozie/share/lib/lib_20170116233431</value>
</property>

6. Modify the "job.properties" file and set the following property to true. The restart the oozie/job

oozie.use.system.libpath=true 

.
