och, ok, thank you. But there is still no prefix so it uses %spark right?

@jzhang I am using Zeppelin 0.6.0 and there is a template Notebook "Zeppelin Tutorial" that uses Java code with no prefix and it works.

Hi, How to configure Java code to work? When I type Java code in the paragraph with no prefix (%) I got NullPointerException in log and nothing on the screen (only word "Error"). Thank you in advance.

@Adi Jabkowsky I had a similar problem to yours once (works till reboot). I typed the values of these parameters: - xasecure.audit.destination.db.user - xasecure.audit.destination.db.password as "plain text" and it worked for me. First one is a MySQL Username which has access to ranger_audit database and second parameter is his password.

Hi @Adi Jabkowsky please check properties: - xasecure.audit.destination.db.user - xasecure.audit.destination.db.password - xasecure.audit.destination.db.jdbc.url - xasecure.audit.destination.db.jdbc.driver and whether "Audit to DB" is checked in Ambari -> Hive -> Configs -> Advanced -> Advanced ranger-hive-audit. Try to type your own values instead of {{variable}}.

@Mats Johansson Thank you for the answer. I did not mention that, but I want to configure High Availability for MySQL aswell. I am going to try Galera + HAProxy in the immediate future.

Hi, I would like to use replication of Hive Metastore database. To do that I installed MySQL Cluster. The problem is that MySQL Cluster needs "ndbcluster" engine for tables to replicate. My default engine is "InnoDB". After converting "hive" tables from "InnoDB" to "ndbcluster" I got strange errors (like "Expected state FINISHED, but found ERROR" or "Error while compiling statement: FAILED: SemanticException java.lang.NullPointerException") when I try to insert data to Hive. Is there any way to workaround this? Doesnt hive support "ndbcluster" engine?

Is this fixed in HDP2.5? Knox 0.9.0 I mean is there a possibility in the new version to filter AD groups? I have over 1000 groups in AD and when Knox tries to authenticate me, AD returns an error "Size limit exceeded".

@mrizvi Actually on my cluster the value of yarn.resourcemanager.address is also 8050 (by default). I did not try your solution yet, but thank you for the answer. I am going to let you know if that works.

@Artem Ervits Thanks for the answer. Actually the problem has gone, because I downgraded MySQL to version 5.7.9 (which was required) from 5.7.13. The problem was about requirements, Ambari needed mysql-community-common and devel of version 5.7.9.
