AuthorizationException: User not allowed to impersonate User

问题

I wrote a spark job which registers a temp table and when I expose it via beeline (JDBC client)

$ ./bin/beeline
beeline> !connect jdbc:hive2://IP:10003 -n ram -p xxxx
0: jdbc:hive2://IP> show tables;
+---------------------------------------------+--------------+---------------------+
|                    tableName                          | isTemporary  |
+---------------------------------------------+--------------+---------------------+
| f238                                                        | true              |
+---------------------------------------------+--------------+---------------------+
2 rows selected (0.309 seconds)
0: jdbc:hive2://IP>

I can view the table. When querying I get this error message

0: jdbc:hive2://IP> select * from f238;
Error: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: ram is not allowed to impersonate ram (state=,code=0)
0: jdbc:hive2://IP>

I have this in hive-site.xml,

<property>
  <name>hive.metastore.sasl.enabled</name>
  <value>false</value>
  <description>If true, the metastore Thrift interface will be secured with SASL. Clients must authenticate with Kerberos.</description>
</property>

<property>
  <name>hive.server2.enable.doAs</name>
  <value>false</value>
</property>

<property>
  <name>hive.server2.authentication</name>
  <value>NONE</value>
</property>

I have this in core-site.xml,

<property>
  <name>hadoop.proxyuser.hive.groups</name>
  <value>*</value>
</property>

<property>
  <name>hadoop.proxyuser.hive.hosts</name>
  <value>*</value>
</property>

full log

Any idea what configuration I am missing?

回答1:

<property>
 <name>hive.server2.enable.doAs</name>
 <value>true</value>
</property>

Also if you want user ABC to impersonate all(*), add below properties to your core-site.xml

<property>
  <name>hadoop.proxyuser.ABC.groups</name>
<value>*</value>
</property>

<property>
 <name>hadoop.proxyuser.ABC.hosts</name>
 <value>*</value>
</property>
