@Scharan  The issue has been resolved. Summarising the resolution as below so that it helps others, As suspected, the  hdp repository was not completely configured. So we deleted all the hdp repos from the servers. Created a new  hdp repo in ambari-server host with the respective urls along with username and password for HDP and HDP-UTILS. Yum clean all, and yum repolist Then started with the ambari server installation as mentioned in the official documentation. Faced issues while installing hive especially with the mysql-connector-jar whose file size was around 24MB. Thanks for your help in providing the correct jar for the installation.  The official documentation is very helpful for beginners like us. Now all the services are up and running successfully. Again Thank you and your team for your help in resolving this issue.   ... View more
