@naveensangam @jepe_desu In reference to Invalid KDC administrator credentials issue raised by @naveensangam I wrote a walkthrough of the solution that resolved the issue for other users like @jepe_desu who had encountered exactly the same problem. @naveensangam can you update the thread if my solution resolved your issue or if not can you share what errors you have. Once you accept an answer it can be referenced by other members for similar issues rather than starting a new thread. Happy hadooping

For me the solution to this issue was just reinstalling the ambari-agent. Maybe it was partially installed somehow.

Thanks for the answers. I don't use Kerberos. Adding the services manually to Ranger worked out. It can connect successfully. I don't know why it didn't add the services automatically to Ranger. Anyway my problem is solved.

ok so after second thinking I think its better to use the latest version that supported - 7.6 instead of 7.5 rhel 7.6 can support HDP 2.6.4 and up ( latest HDP version ) rhel 7.6 can support 2.6.2.2 , 2.7.3 , 2.7.4 ambari version and when current rhel version is 7.2 and we want to add rhel 7.6 OS version then its fully recommended to upgrade 7.2 to 7.6

@Harisc4y Bingooooooooo ! You are trying to install CDH on Operating System that is not certified no wonder all this headache I can now go to sleep. We NEVER stress enough before embarking on deploying a software HDP or CDH you MUST read the vendor's release notes and most important the compatibility matrix. Not heeding to these pre-requisites always leads to a very bad first experience. I downloaded and fired up your VM successfully, I then started form the basics Memory, CPU and networking then I saw a strange UI so checking the version confirmed my fears Unsupported OS Cloudera Compatability Matrix Reference: https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_os_requirements.html#c63_supported_os Currently, Centos/RHEL 7.6 is the latest compatible version so no need to proceed further with investigations Happy hadooping
