Hello everyone, It seems like there is a bug in the newest Ambari version. I took this link as stated in the installation guide of Hortonworks: "wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.6.0.0/ambari.repo -O /etc/yum.repos.d/ambari.repo", but when I changed to "wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.5.0.3/ambari.repo -O /etc/yum.repos.d/ambari.repo" the installation went through also with HDP2.6.3. Does anyone know why? But anyways now it is working :-). Best regards, Christian ... View more

@Geoffrey Shelton Okot Thank you very much. Next time I will open a new Thread. Here is the output of the query: ambaridatabase.jpg ambari=> select host_id, host_name, last_registration_time, public_host_name from hosts; host_id | host_name | last_registration_time | public_host_name ---------+---------------------------+------------------------+--------------------------- 1 | master1.XXXXXX.de | 1512415944737 | master1.XXXXXX.de 2 | slave1.XXXXXX.de | 1512415945031 | slave1.XXXXXX.de 4 | slave3.XXXXXX.de | 1512415948038 | slave3.XXXXXX.de 3 | slave2.XXXXXX.de | 1512415948901 | slave2.XXXXXX.de 5 | master2.XXXXXX.de | 1512415944037 | master2.XXXXXX.de Thank you so much, Christian ...

Hi @Geoffrey Shelton Okot I'm facing the same problem we had before, but I'm using ambari-2.6.0.0 to install HDP2.6.3. The workaround doen't work for me because in step 5, when I have to decide on which node I have to install which service, there is no server listed, althought it was green in step 3. I worked through all suggestions and did everything twice in minimum but I'm totally not able to install Hortonworks and this is really frustrating, because I did it so many times before. Maybe you can give me a final hint to proceed here. Attaches the Screenshot: ambari.jpg Thanks in advance and best regards, Christian ... View more
