I have recently installed HDP 3.0. I was trying to work on below tutorial,
Since Apache nifi was needed, as per the instructions provided in below link, i implemented the steps.
When i arrived at below step, the SSH command resulted in an error, 'Connection refused'
Once the container is created, SSH into the HDF sandbox:
ssh email@example.com -p 12222 # password: greenhadoop
I understood that i need to install HDF sandbox. So i tried to upgrade Ambari and HDP before upgrading HDF sandbox to the whole set up. Here i followed below steps as mentioned:
The above link was helpful in some places. In some places, i was running to permission denied error. This messed up the whole installation (if i am not wrong) leading to lot of critical alerts in Ambari. Finally i thought of getting the Whole HDP uninstalled and was thinking about starting everything from the scratch.
The pain point is when uninstalling HDP. As found in below links; i referred and tried to uninstall HDP so that i can start with a new set of installtion for HDP and HDF afresh.
Above links have several breaking points and I was not able to successfully complete the uninstall.
Now i am stranded and not able to proceed further with my POC. Appreciate if someone can help with you inputs to start everything afresh. All i am planning to do is to perform a POC and learn NIFI integration with Kafka. I appreciate your feedback. Thanks in advance.
The above question was originally posted in the Community Help track. On Sat Jul 6 20:52 UTC 2019, a member of the HCC moderation staff moved it to the Sandbox & Learning track. The Community Help Track is intended for questions about using the HCC site itself, and the original question is really about The HDP Sandbox.
Thanks for mapping my question to the right team.
I would really appreciate if anyone could share their experience or thoughts.
Appreciate your inputs. Thanks
