@Leonardo Apolonio Either you will need to run ambari server azs "root" user. (OR) You will need to configure the non root user "hydra" in the "sudoer" list. . Regarding your query: "Does ambari-server user need sudo privileges?" If using non root user then yes, ambari server's user needs to be configured as sudo user. Please refer to the following docs: (Ambari server Sudoer config) 1. https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.3/bk_ambari-security/content/sudo_defaults_server.html 2. https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.3/bk_ambari-security/content/sudoer_configuration_server.html 3.

@Leonardo Apolonio We see the error as conflict between packages: file /usr/lib/python2.6/site-packages from install of ambari-agent-2.6.1.0-143.x86_64 conflicts with file from package ambari-server-2.6.1.0-0.x86_64 . This error indicates that you have AmbariServer package of version 2.6.1.0.0 but trying to install Ambari-Agent of version 2.6.1.0-143 (slightly higher). Which is causing the conflict. . Please check if you have duplicate ambari repos like (2.6.1.0-143 as well as 2.6.1.0.0 both) on the same host? In that case remove the Old unwanted ambari repo from the mentioned dir and then perform a yum clean. # grep baseurl /etc/yum.repos.d/* | grep ambari So can you please try this: # yum clean all . Then retry the agent installation or try the "yum upgrade ambari-server" first and then upgrade the agent. # sudo yum upgrade ambari-server # sudo yum upgrade ambari-agent . ... View more
