Hmm that's interesting. During the process I changed the admin user/pass in the Ambari admin and I restarted Atlas. However those credentials didn't work.  I just tried holger_gov/holger_gov and that also did not work. Tried restarting again and then the combination I manually configured did work...   So I'm up and running again for the moment! Thanks. ... View more

@naveensangam  @jepe_desu  In reference to Invalid KDC administrator credentials issue raised by @naveensangam    I wrote a walkthrough of the solution that resolved the issue for other users like @jepe_desu  who had encountered exactly the same problem.  @naveensangam  can you update the thread if my solution resolved your issue or if not can you share what errors you have. Once you accept an answer it can be referenced by other members for similar issues rather than starting a new thread.    Happy  hadooping   ... View more
