To encrypt LDAP bind password in zeppelin Shiro configuration follow below steps: 1. Removed system password line from the config (this line contained the password for the system user that is doing the LDAP lookups) 2. Added the following line in shiro.ini: ldapRealm.hadoopSecurityCredentialPath=jceks://file/home/zeppelin/conf/zeppelin.jceks 3. Run the following command as Zeppelin user on Zeppelin host: # hadoop credential create ldapRealm.systemPassword -provider jceks://file/home/zeppelin/conf/zeppelin.jceks
#Entered password <test> Where <test> is my password 4. Confirmed that file has 700 attributes 5. Restart Zeppelin

Jdbc interpreter is will take default queue to run a job.
To run the job in specific queue add the queue name in hive.url property in JDBC interpreter settings as shown below
hive.url=jdbc:hive2://<zookeeper quorum>/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2?tez.queue.name=<Queue Name>
EXAMPLE:
hive.url= jdbc:hive2://c186-node2.-labs.com:2181,c186-node3.-labs.com:2181,c186-node4.-labs.com:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2?tez.queue.name=sai
Where sai is my queue name.
To check and confirm execute below query in zeppelin using JDBC interpreter and check-in Yarn Resource manager UI
%jdbc(hive)
show databases;
use <database name>;
show tables;
select count (*) from <table name>;
