Hi, my Zeppelin installation has corrupted after some changes and I could not find the solution to the problem. So I tried to delete Zeppelin from Ambari UI -also I tried it by using REST API- but after delete operation, all configurations and directories which Zeppelin has seem still present. I want to install Zeppelin on the same host which I deleted on and when I try it, Ambari just does some operations, which are not the complete installation processes, and after that Zeppelin seems installed but not working because of the corruption. I wonder that when installing any service the first time by using Ambari, it creates required dirs, conf files and etc but why it can not do reverse operations when deleting the service? What can I perform to delete and install the same service on the same host correctly? I had tried to delete all zeppelin dirs, confs, and files from the host and HDFS. Also, I deleted Zeppelin users from all hosts including host directories. Now Ambari still does not install Zeppelin properly. Is there a conf file like inventory I missed? Any suggestions, please? Thanks.
