@schnell Glad you were able to find the remnant that blocked re-install. Here is my SO reply, which gives some details about how to completely remove HDP and components from node filesystem... With ambari, any service that is deleted with the UI, will still exist on the original node(s) the service was installed on. You would need to manually remove them from the node(s). This process is hard to find documentation on, but basically goes as follows: Delete the application from file system locations such as /etc/ /var/ /opt/ etc Remove user accounts/groups You can find some more details in this blog post here which goes into some of the detail for completely removing HDP. Just follow steps for single service. https://henning.kropponline.de/2016/04/24/completely-uninstall-remove-hdp-nodes/ https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.3.2/bk_installing_manually_book/content/ch_uninstalling_hdp_chapter.html https://gist.github.com/hourback/085500397bb2588964c5 If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.
