Question

使用Hive查询运行Oozie工作流时出错。这是工作流程

<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"/>

这是oozie属性文件

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

这是我得到的错误：

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]

但是命名空间存在，我可以查询其中的表。

这里有什么问题？请帮忙。我使用CDH 5.5.2 Running Hive 1.0

经过对互联网的不懈研究，我能够解决问题的解决方案。我添加了一个配置，以便将Metastore服务器用于Hive作业，并且它可以工作。

以下是我对Hive行动的所作所为。

....
<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>
....

注意：如果您正在尝试修复类似问题，请相应地更换hive metatore ip。要获取Metastore详细信息，请检查位于/ etc / hive / conf目录中的hive-site.xml文件。
