使用带有Herberos的Hive Metastore服务器进行Oozie Hive动作

Question

I'm using CDH5. I have set up a Hive Metastore to use kerberos. ie the hive-site.xml has the following properties

<property>
  <name>hive.metastore.sasl.enabled</name>
  <value>true</value>
</property>

<property>
  <name>hive.metastore.kerberos.keytab.file</name>
  <value>/etc/hive/conf/hive.keytab</value>
</property>

<property>
  <name>hive.metastore.kerberos.principal</name>
  <value>hive/hive-metastore.example.com@example.COM</value>
</property>

The logs show no errors on starting the hive-metastore service.

I'm trying to run a hive action in an oozie workflow. The oozie-site.xml file has the following property

<property>
  <name>oozie.credentials.credentialclasses</name>
  <value>hcat=org.apache.oozie.action.hadoop.HCatCredentials</value>
</property>

And the workflow xml file has the credentials tag

<credentials>
    <credential name='hive_credentials' type='hcat'>
          <property>
              <name>hcat.metastore.uri</name>
              <value>thrift://hive-metastore.example.com:9083</value>
          </property>
          <property>
              <name>hcat.metastore.principal</name>
              <value>hive/hadoop-metastore.example.com@example.COM</value>
          </property>
     </credential>
</credentials>

The hive action refers to the credentials using the 'cred' attribute.

<action name="hive" cred="hive_credentials">
    <hive xmlns="uri:oozie:hive-action:0.2">
        <job-tracker>${jobTracker}</job-tracker>
        <name-node>${nameNode}</name-node>
        <job-xml>${appPath}/hive-site.xml</job-xml>
        <configuration>
            <property>
                <name>mapred.job.queue.name</name>
                <value>${queueName}</value>
            </property>
        </configuration>
        <script>${appPath}/queries.hql</script>
    </hive>
    <ok to="pass"/>
    <error to="fail"/>
</action>

When I try to run this workflow, I get the following error.

Exception in addtoJobConf

Any idea what could be causing this issue?

Answer 1

I have a working workflow that uses:

hive/_HOST@example.COM

as the hcat.metastore.principal , instead of:

hive/hadoop-metastore.example.com@example.COM

Can you try?
