Hi all,
My Hive action is failing with the following error:

Error Message: org/apache/hadoop/hive/conf/HiveConf
This is my hive action:
<hive xmlns="uri:oozie:hive-action:0.2">
<job-tracker>[private DNS name]:8050</job-tracker>
<name-node>hdfs://[private DNS name]:8020</name-node>
<script>score_tweets.sql</script>
</hive>
job.properties:
nameNode=hdfs://[private DNS name]:8020
jobTracker=[private DNS name]:8050
queueName=default
oozie.libpath=${nameNode}/user/oozie/share/lib
oozie.wf.application.path=${nameNode}/user/root/oozie
I am using oozie 4.0.0 on HDP 2.1
Googling produced some useful things (see
https://support.pivotal.io/hc/en-us/articles/202563453-Oozie-hive-action-fails-with-java-lang-NoClassDefFoundError-org-apache-hadoop-hive-conf-HiveConf-
and
http://stackoverflow.com/questions/18369605/error-while-running-hive-action-in-oozie),
but I've tried these, and I'm still getting the same error.
I have:
- ensured that hive-exec is in /user/oozie/share/lib (also in
/user/root/share/lib as this job is run as root)
- ensured that hive-exec exists in a path in the common.loader property in
the catalina.properties file
- even put the 'oozie.service.WorkflowAppService.system.libpath' property
into hive-site.xml like the stackoverflow answer suggested, even though
this doesn't make much sense to me (it is in oozie-site.xml and I have
overriden it to point hard-coded to /user/oozie/share/lib)
- not done anything with hive-default.xml since the documentation says this
is now ignored.
Does anyone have any suggestions?
Thanks,
Charles
