Hi Sheng, It's my bad and I didn't express this point clearly, and it needs to be stated that the ambari plugin is not a task plugin for DS, but a deployment plugin allow user deploying DS by Ambari. its purpose is to facilitate users to deploy DS in Ambari. Unfortunately, It currently lacks maintenance and only supports DS 1.3.0 and 1.3.3 deployments. And it has not been updated for two years [1]. The point it the architecture of 2.0 has been significantly modified compared to the architecture of 1.3.3, which means that he is no longer applicable to 2.0.
It would be exciting if there were contributors willing to support ambari's plugin beyond 1.3.3, or even beyond 2.0, but as of now there are still no body, and there is no feedback from the community about ambari plugin deployment, so we believe that he is no longer used by user, and no contributors can be found in the community. (Of course if there are any, please let me know in this email thread) This is why I think he should be removed.
