I'm not finding much information about this. Which driver version is this occurring with?

Hi binghamc, Can you enable debug logging (page 22 of this doc, select level 5) for more insight into the error?

Hi parnigot, That upgrade should be fine. You would still be in the same major version. Here's some more information on upgrades, FYI.

Hi Ashish, Is the Java client in the VM or just on the same host? If the same krb5.conf file as that in the VM exists and connection the the KDC server resolves properly, you should be able to kinit from another host.

Hi parnigot, You can try selecting those specific principals and clicking "Regenerate Selected". Alternatively, you could just go into the KDC or AD and delete the principals there.

Hi stumilus, Not sure if this is answering the question but just some observations: That export looks to be using the API to retrieve the information. The information displayed for each application should match what is shown in the Resource Manager Web UI.

Hi Kranach, Impala has a configuration for limiting what queries a non-admin user is able to see. Impala > Configuration > Non-Admin Users Query List Visibility Settings. Similarly, YARN configurations contain Non-Admin Users Applications List Visibility Settings. Does this help?

Hi mtrepanier, Keystores can be created with keytool. I believe you only need to have the server certificate in the keystore specified in the connection string. The CA file should already be in the truststore.

Interesting - what information do we receive when logging is enabled? What is set in HDFS > Hadoop User Group Mapping?

I don't believe we've done much testing with CDH and Composite Group Mappings but from what I understand, you'd specify the configurations for each LDAP (AD) provider individually - in the example provided in the previous link, we can see how each LDAP URL is provided; if other LDAP configurations differ such as bind user, bind password, filters, etc. those can be entered as additional properties. All of this would go in the cluster wide core-site.xml safety valve (in HDFS configurations). Again, haven't tested it but there are some who use it. A more robust approach would be to use tools like Centrify, VAS, SSSD, etc. to handle the AD/Linux integration.

I don't have time at the moment to check the QuickStart VM but let's check the /usr/lib/ hive/lib location (rather than ~/parcels or ~/lib). Also, the ADD JAR command has to be run from within Beeline.

Sure, glad to help. Does hive-contrib.jar exist at /opt/cloudera/parcels/CDH/lib/hive/lib/hive-contrib.jar? You can navigate to this directory to verify. Was the ADD JAR command run with Beeline? What's the full error output?

Hi Sunil, Was the same connection string in #1 also used prior to upgrading CDH? Let's enable logging level 5 for more detailed information. See page 22 of this doc.

Hi Tom, Once you've completed the collection of diagnostic data, there should be an option to Download Result Data at the top of the Command window. You can then select where you want to save the ZIP file. The button will look something like this: Cheers

@saranvisa Are you having the same issue? Or are you working with the OP? Just trying to understand.. Using the hive user should work properly. If you want to use a different user (eg. hdpsysuser), core-site.xml will need entries like the following: <property> <name>hadoop. hdpsysuser .server.hosts</name> <value>*</value> </property> <property> <name>hadoop. hdpsysuser .server.groups</name> <value>*</value> </property> Was there a particular reason impersonation is needed? Typically, Sentry is recommended for enforcing access policies.

Hi fcausa, I assume that <paht> is just a placeholder and not the literal text in the line setting java.security.auth.login.config. The credential cache will be checked first (jaas.conf has useTicketCache=true) so we'll need to make sure a valid ticket is available first. That is probably why running kinit first works. Also, is the REALM specified for the principal in jaas.conf the same as the default realm specified in krb5.conf (assuming your example of kinit working was with just the base username)? However, for more details on the error, you can also enable debugging messages by adding LogLevel=3;LogPath=<file_path> to the connection string.

Hi Sidharth, This page has information on topics covered (also mentioned in many of the anwered posts in the right sidebar). It’s tough to comment on difficulty - that’s dependent on each person. What I do know is that it is a multiple choice exam. Good luck!
