Question

我需要安排与安全hbase交互的oozie Java操作，因此我需要为Java操作提供hbase凭据。我使用的是安全的hortonworks 2.2环境，我的工作流XML如下所示

<workflow-app xmlns="uri:oozie:workflow:0.4" name="solr-wf">
    <credentials>
         <credential name="hbase" type="hbase">
         </credential>
      </credentials>

    <start to="java-node"/>
    <action name="java-node" cred="hbase">
        <java>  
             <job-tracker>${jobTracker}</job-tracker>
             <name-node>${nameNode}</name-node>
             <main-class>com.test.hbase.TestHBaseSecure</main-class>
            <arg>${arg1}</arg>
        </java>
        <ok to="end"/>
        <error to="fail"/>
    </action>
    <kill name="fail">
        <message>Java failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <end name="end"/>
</workflow-app>

我还修改了oozie属性以包含HbaseCredentials Class

oozie.credentials.credentialclasses=hcat=org.apache.oozie.action.hadoop.HCatCredentials,hbase=org.apache.oozie.action.hadoop.HbaseCredentials

但是我无法运行它抛出错误的工作，下面是stacktrace

java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration

其他工作运行良好，它只是hbase交互失败的工作。我已经在我的lib目录中包含了所有的hbase jar，我无法弄清楚这个问题。

更新了workflow.xml：

<workflow-app xmlns="uri:oozie:workflow:0.4" name="${appName}">
<credentials>
        <credential name="hbase-cred" type="hbase">
            <property>
                <name>hbase.master.kerberos.principal</name>
                <value>hbase/_HOST@ABC.COM</value>
            </property>

            <property>
                <name>hbase.master.keytab.file</name>
                <value>/etc/security/keytabs/hbase.service.keytab</value>
            </property>

            <property>
                <name>hbase.regionserver.kerberos.principal</name>
                <value>hbase/_HOST@ABC.COM</value>
            </property>

            <property>

                <value>/etc/security/keytabs/hbase.service.keytab</value>
            </property>

            </property>

            <property>
                <name>hbase.zookeeper.quorum</name>
                <value>dev1-dn2,dev1-dn3,dev1-dn1</value>
            </property>

            <property>
                <name>zookeeper.znode.parent</name>
                <value>/hbase-secure</value>
            </property>
        </credential>


    </credentials>
    <start to="java-node" />
    <action name="java-node" cred='hbase-cred'>
        <java>
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <main-class>com.test.hbase.TestHBaseSecure</main-class>
        </java>
        <ok to="end" />
        <error to="fail" />
    </action>
    <kill name="fail">
        <message>Java failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <end name="end" />
</workflow-app>

Answer 1

在HDP2.2.8上测试该溶液：

复制到以下jars的/usr/hdp/current/oozie-server/oozie-server/webapps/oozie/WEB-INF/lib：
- HBase的客户端 - * - hadoop2.jar
- HBase的共用 - * - hadoop2.jar
- HBase的协议 - * - hadoop2.jar
- HBase的服务器 - * - hadoop2.jar
- HTRACE核-2.04.jar
重启Oozie服务器。

Answer 2

这些“凭据”由 Oozie服务管理，而不是由您的工作管理。

所以，如果HortonWorks在包装发行版方面做得不错......

hbase-common-*-hadoop2.jar将部署在安装/usr/hdp/current/oozie-client/libserver/
JAR不会在定义上与其他JAR冲突 class org.apache.hadoop.conf.Configuration
最后你可以管理HBase Oozie的证书

我们的Prod群集上安装的HDP2.2.4并非如此。 Arghh。 那该死的东西在该死的释放中被打破了。您必须自己管理Kerberos票证，从HDFS下载密钥表<file>并在实际连接到HBase之前创建TGT。我们去过那里。

请查看that post，了解有关如何完成的一些见解。
