While the work around did not work exactly, it pointed us in the correct direction of working with the impersonations and making sure that those were all set correctly. Thank you.

The Livy Logs are showing that the HiveContext is starting fine, but for sanity's sake I tried your method of configuration and after the changes and restarts, it is still outputting the same error.

I have setup a Livy Interpreter through Zeppelin and am trying to run the simple %livy.pyspark
sc.version Cannot Start Spark but to no avail.
%spark sc.version res10: String = 1.6.2 however, returns the version just fine. The livy interpreter configs look like such: livy.spark.master yarn-cluster
zeppelin.interpreter.localRepo /usr/hdp/current/zeppelin-server/local-repo/....
zeppelin.livy.concurrentSQL false
zeppelin.livy.create.session.retries 120
zeppelin.livy.keytab /<location_of_keytab>/zsk.keytab
zeppelin.livy.principal <zeppelin_principal>
zeppelin.livy.url http://<hostname>:8998
I have followed the instructions provided here https://community.hortonworks.com/articles/80059/how-to-configure-zeppelin-livy-interpreter-for-sec.html in entirety. The cluster is Kerberized as well as Zeppelin being synced to Active Directory. Also, the Resource Managers are in HA and I am seeing a few errors in the livy log regarding refused connections to :8032 (Default Port for RM Admin) See Below for Stacktrace: WARN Client: Failed to connect to server: <Hostname>/<IP>:8032: retries get failed due to exceeded maximum allowed retries number: 0

Wonderful! If you could close the other question you had posted and accept my answer it would be greatly appreciated! It is a bit funky how it works, but as you make sure you have the correct hive-site.xml in the Spark conf, you should be okay as all of your other configs looked correct. For some reason the hive-site.xml in Spark doesn't have the same template as Hive's. Ambari will notice the hive-site.xml and overwrite it in the Spark directory whenever Spark is restarted, thus the need to copy it over again, I have a cronjob set up to cp the hive-site.xml over every 5 minutes so I don't have to worry about that, something you might think about doing.

I ran into this same issue a few weeks ago using Zeppelin to run Livy, make sure that you copy over the Hive hive-site.xml into the spark/conf directory on every node in the cluster, this will alleviate the inability to connect to the Hive Metastore more often than not. Please let me know the status after you try this or if you have already done that, so we can continue troubleshooting.

They are both technically managed by ambari, so if you are to restart spark, you will need to copy the hive-site.xml back over to overwrite the Spark's hive-site.xml as sometimes they are not the same

Spark uses the one in its directory to connect to hive when initializing a hive context, you can overwrite the spark hive-site with the hive's hive-site and it is recommended you do that in order to be able to connect to hive from Spark. This is what I did in order to be able to run Livy.Spark within Zeppelin and was able to connect to Hive via this method.

Hello All, Does anyone know of a way to configure Zeppelin so that it will automatically set notebook permissions when creating a new note? We are using shiro to authenticate via AD and are fine tuning the groups permissions in that area, but I am curious to see if there's a way to have a note set default permissions to anything other than (*) for owner, read, write. Environment: Our environment is currently on HDP-2.5.3.0-37 which houses Zeppelin release 0.6.2, we plan to upgrade to HDP 2.6+ in the coming months which houses Zeppelin release 0.7.0. Target Outcome:
When `user1` creates a note, the note permissions (available through the padlock symbol on the note page) will automatically populate to Owner: `user1`, Write: `none`, Read: `none`. Many thanks in advance to any help, Colton
