hadoop - Oozie hive action with kerberos on HDP-1.3.3 -


i'm trying execute hive script oozie hive action on kerberos enabled environment.

here workflow.xml

<action name="hive-to-hdfs">     <hive xmlns="uri:oozie:hive-action:0.2">         <job-tracker>${jobtracker}</job-tracker>         <name-node>${namenode}</name-node>         <job-xml>hive-site.xml</job-xml>         <configuration>             <property>                 <name>mapred.job.queue.name</name>                 <value>${queuename}</value>             </property>         </configuration>         <script>script.q</script>         <param>hive_export_time=${hiveexporttime}</param>     </hive>     <ok to="pass"/>     <error to="fail"/>

i'm facing issue when trying connect hive metastore.

when disable kerberos security workflow works fine

to enable oozie hive action function on secured cluster need include <credentials> section credential of type 'hcat' workflow.

your workflow like:

<workflow-app name='workflow' xmlns='uri:oozie:workflow:0.1'>     <credentials>         <credential name='hcat' type='hcat'>             <property>                 <name>hcat.metastore.uri</name>                 <value>hcat_uri</value>             </property>             <property>                  <name>hcat.metastore.principal</name>                 <value>hcat_principal</value>             </property>         </credential>     </credentials>      <action name="hive-to-hdfs" cred="hcat">         <hive xmlns="uri:oozie:hive-action:0.2">             <job-tracker>${jobtracker}</job-tracker>             <name-node>${namenode}</name-node>             <job-xml>hive-site.xml</job-xml>             <configuration>                 <property>                     <name>mapred.job.queue.name</name>                     <value>${queuename}</value>                 </property>             </configuration>             <script>script.q</script>             <param>hive_export_time=${hiveexporttime}</param>         </hive>         <ok to="pass"/>         <error to="fail"/>     </action> </workflow>

there oozie documentation feature.
