I get an error while running an Oozie workflow with Hive queries.

Here is the workflow

<workflow-app xmlns='uri:oozie:workflow:0.5' name='reporting_W_errorAuditHiveQueryExe'>
	<start to="hive_report_fork"/>
	<fork name="hive_report_fork">
		<path start="hiveGSRLfile"/>
		<path start="hiveNGSRLfile"/>
		<path start="hiveNGsrlRAfile"/>
	</fork>
	<action name="hiveGSRLfile">
		<hive xmlns='uri:oozie:hive-action:0.2'>
			<job-tracker>${jobTracker}</job-tracker>
			<name-node>${nameNode}</name-node>
			<script>${dir}/gsrlQery.hql</script>
			<param>OutputDir=${jobOutput}</param>
		</hive>
		<ok to="joining"/>
		<error to="joining"/>
	</action>
	<action name="hiveNGSRLfile">
		<hive xmlns='uri:oozie:hive-action:0.2'>
			<job-tracker>${jobTracker}</job-tracker>
			<name-node>${nameNode}</name-node>
			<script>${dir}/nongsrlQuery.hql</script>
			<param>OutputDir=${jobOutput}</param>
		</hive>
		<ok to="joining"/>
		<error to="joining"/>
	</action>
	<action name="hiveNGsrlRAfile">
		<hive xmlns='uri:oozie:hive-action:0.2'>
			<job-tracker>${jobTracker}</job-tracker>
			<name-node>${nameNode}</name-node>
			<script>${dir}/nongsrlRAQuery.hql</script>
			<param>OutputDir=${jobOutput}</param>
		</hive>
		<ok to="joining"/>
		<error to="joining"/>
	</action>
	<join name= "joining" to="Success"/>
	<action name="Success">
		<email xmlns="uri:oozie:email-action:0.1">
			<to>${failureEmailToAddress}</to>
			<subject>Success</subject>
			<body>
				The workflow ${wf:name()} with id ${wf:id()} failed
				[${wf:errorMessage(wf:lastErrorNode())}].
			</body>
		</email>
		<ok to="end" />
		<error to="fail" />
	</action>
	<action name="failure">
		<email xmlns="uri:oozie:email-action:0.1">
			<to>${failureEmailToAddress}</to>
			<subject>Failure</subject>
			<body>
				The workflow ${wf:name()} with id ${wf:id()} failed
				[${wf:errorMessage(wf:lastErrorNode())}].
			</body>
		</email>
		<ok to="end" />
		<error to="fail" />
	</action>
	<kill name="fail">
		<message>Workflow failed</message>
	</kill>
	<end name="end"/>
</workflow-app>

And here is the oozie properties file

oozie.wf.application.path=${deploymentPath}/workflows/errorAuditHiveQueryExe.xml
deploymentPath=/user/amin/deploy_178
jobTracker=localhost:8032
nameNode=hdfs://nameservice1
dir=${deploymentPath}/data-warehouse/temp
failureEmailToAddress=amin@dnb.com
jobOutput=${dir}
oozie.use.system.libpath=true

Here is the error I get:

FAILED: SemanticException [Error 10072]: Database does not exist: testnamespace 
Intercepting System.exit(10072)
Failing Oozie Launcher, Main class [org.apache.oozie.action.hadoop.HiveMain], exit code [10072]

However the namespace exist and I can query the tables inside it.

What could be wrong here? Please help.

After a tireless research on the internet I was able to crack the solution for the issue. I have added a configuration to use the metastore server for the Hive job and it worked. Here is what I did to the Hive action.

....
    <hive xmlns='uri:oozie:hive-action:0.2'>
    <job-tracker>${jobTracker}</job-tracker>
    <name-node>${nameNode}</name-node>
    <configuration>
                    <property>
                     <name>hive.metastore.uris</name>
     <value>thrift://10.155.1.63:9083</value>
                    </property>
                </configuration>
    <script>${dir}/gsrlQery.hql</script>
    <param>OutputDir=${jobOutput}</param>
    </hive>
    ....

Note: replace the hive metatore ip accordingly if you are trying to fix a similar problem. To get the metastore details check the hive-site.xml file located in /etc/hive/conf dir.
