As you know, CM provide parcel/csd to make you easy to integrate third-party component with CM.
Do you guys know where is CDH self's CSD? How can i find in CDH Cluster?
CSD is Custom Service Descriptor and as the name suggests it is a file (jar) that contains the description and logic for Cloudera Manager to manage that service.
CM is a part of CDH and it's not a custom service. therefore, it doesn't have a CSD.
If you want to add a CSD and you didn't change the installation defaults, then the directory where you need to place the CSD should be /opt/cloudera/csd
