to Ranger: true or false ??

Subject: Re: Hive admin user behavior

If the hive.server2.enable.doAs parameter is set to false, then the underlying 
jobs in HDFS are run as "hive" user. This is a better security model as the 
underlying HDFS file permissions can be set to be owned only by "hive" user and 
end user would not be able to access files directly without going through 
Hiveserver2

Yes I am using beeline client for testing purpose and hiveserver2 jdbc client.


Still I have confusion about "hive.server2.enable.doAs" property-


As per wiki documentation 
(https://cwiki.apache.org/confluence/display/Hive/Setting+Up+HiveServer2​):

By default HiveServer2 performs the query processing as the user who submitted 
the query. But if the following parameter is set to false, the query will run 
as the user that the hiveserver2 process runs as.

hive.server2.enable.doAs – Impersonate the connected user, default true.


As per my understanding if this property is set to false, all queries will run 
as the user who started hiveserver2 process. so we should set "true" value for 
this property to run the query as user who submitted the query.


Please let me know your thoughts on this.

Yes, if you are using Ranger, then you have to set appropriate permissions on 
Ranger. It helps in plugging any backdoor loop holes.

I am also assuming you are using beeline client or JDBC.

One more thing, we recommend hive.server2.enable.doAs=false.

Thanks

Hi All,


When deploying hive, I have defined below configuration for hiveserver2 in 
configuration file "hive-site.xml":


<property>
    <name>hive.server2.enable.doAs</name>
    <value>true</value>
</property>
<property>
    <name>hive.users.in.admin.role</name>
    <value>hanish</value>
</property>

<property>
    <name>hive.security.authorization.manager</name>
    
<value>org.apache.hadoop.hive.ql.security.authorization.plugin.sqlstd.SQLStdHiveAuthorizerFactory</value>
</property>
<property>
    <name>hive.security.authorization.enabled</name>
    <value>true</value>
</property>
<property>
    <name>hive.security.authenticator.manager</name>
    
<value>org.apache.hadoop.hive.ql.security.SessionStateUserAuthenticator</value>
</property>

<property>
        <name>hive.security.authorization.enabled</name>
                <value>true</value>
</property>


I have added "hanish" user to admin user list (Property- 
hive.users.in.admin.role ) so it should be able to fetch schema of all tables. 
But i am getting permission denied error.

I want one user to define as admin user who can fetch schema of all tables. If 
I give admin permissions or select permissions from ranger-UI to a user for 
databases=* and tables = * then its working fine and that user is able to fetch 
schema for all tables. But  as per hive configurations if user is defined as 
admin by mentioning " hive.users.in.admin.role​" then that user is not behaving 
as admin.

Please let me know the expected behavior.

Is Ranger overrides behavior of hive property " hive.users.in.admin.role​" ??
