How to configure Ambari Hive View for Kerberized cluster
How to configure Ambari Hive View for Kerberized cluster – This tutorial has been successfully tried and tested on HDP-22.214.171.124 and Ambari 126.96.36.199
I have my HDP Cluster Kerberized and Ambari has been configured for SSL.
Note – Steps are same for Ambari with or without SSL.
Please follow below steps for Configuring Hive View on Kerberized HDP Cluster.
Step 1 – Please configure your Ambari Server for Kerberos with the steps mentioned in below article. Please follow steps 1 to 5.
Step 2 – Please add below properties to core-site.xml via Ambari UI and restart required services.
Note – If you are running Ambari Server as root user then add below properties
If you are running Ambari server as non-root user then please add below properties in core-site.xml
Please replace <ambari-server-user> with user running Ambari Server in above example.
I’m assuming that your ambari server principal is ambari-server@REALM.COM, if not then please replace ‘ambari-server’ with your principal’s user part.
Step 3 – Create user directory on hdfs for the user accessing hive view. For e.g. in my case I’m using admin user to access hive view.
sudo -u hdfs hadoop fs -mkdir /user/admin sudo -u hdfs hadoop fs -chown admin:hdfs /user/admin sudo -u hdfs hadoop fs -chmod 755 /user/admin
Step 4 – Goto Admin tab –> Click on Manage Ambari –> Views –> Edit Hive view ( Create a new one if it doesn’t exist already ) and configure settings as given below
Note – You may need to modify values as per your environment settings!
After above steps, you should be able to access your hive view without any issues. If you receive any error(s) then please check /var/log/ambari-server/ambari-server.log for more details and troubleshooting.
