Hi Nagesh,
Please find two pictures below related to your requested rest api information. they are https://{your_management_server_url}:8443/serengeti/api/distros and https://your_management_server_url:8443/serengeti/api/distros/{distroName}
The first one will get all configured hadoop distributions, and the the second one will get the specific distribution. Please make sure you need to login the server before you can call any rest apis. Also in BDE 1.0/1.1, rest apis are not public formally.
Thanks,
Jun
