Hi @pra_big, Please do not add onto a solved thread from 5 years ago. It is very unlikely that the current issue you face is identical so it is best to start a new conversation. Please outline what you are trying to do, what you expect to have happen, and what is actually occurring. From your description, it appears you are running a script that may be an Oracle script (mammoth). That is not a Cloudera Script, so please consult with the vendor that supplied you with "mammoth" if you are need assistance with it. It is hard to tell what you are asking about with respect to the host in Cloudera Manager... if you want to delete a host in CM, Go to the Hosts tab, select "All Hosts". Then, find the host you wish to delete, check the box next to it and then choose "delete" from the drop-down menu. maybe you could show screen shots or explain more about what you are having trouble with. NOTE: when the Cloudera Manager Agent heartbeats to CM, CM identifies the host by "uuid" not hostname. So, if you re-imaged and accidentally reused a UUID from another host, that could lead to some confusion. We need to clearly understand what problem you are seeing to provide the best help.
