我需要安排一个与安全 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

<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 类

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作业，下面是堆栈跟踪

java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration
    at org.apache.oozie.action.hadoop.HbaseCredentials.copyHbaseConfToJobConf(HbaseCredentials.java:60)

    at java.lang.Thread.run(Thread.java:745)

其他作业运行良好，只有与 hbase 交互的作业失败。我已将所有 hbase jar 包含在我的 lib 目录中，但我无法找出问题所在。

更新的 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>

            </property>

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

            <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>

最佳答案

此解决方案已在 HDP2.2.8 上测试:

1. 将以下 jars 复制到 /usr/hdp/current/oozie-server/oozie-server/webapps/oozie/WEB-INF/lib:

   • hbase-client-*-hadoop2.jar
   • hbase-common-*-hadoop2.jar
   • hbase-protocol-*-hadoop2.jar
   • hbase-server-*-hadoop2.jar
   • htrace-core-2.04.jar

2. 重启 Oozie 服务器。

关于hadoop - 在 oozie Java Action 中传递 HBase 凭据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33212535/
