It seems that the issue was not about hbase, but instead related to the namenode. Performing a bootstrapStanby after a backup resolved the issue. The biggest concern is that this was done without putting the cluster into safe mode, since the second namenode could not start up.

@scott powers As of Ambari 2.7, Ambari authenticates with an MIT KDC more securely - using Kerberos. To do this, it must call kinit and specify the kadmin service principal. kinit -c <path> -S kadmin/<kadmin server FQDN>@<realm> <principal> There may be one of two issue a play causing you an issue. 1) The KDC Administrator host is not set to the FQDN of the host there the kadmin server is running 2) The KDC does not have a principal like kadmin/<kadmin server FQDN>@<realm> Fixing #1 may be done by editing the Kerberos service configurations via Ambari. After restarting the Kerberos service, you should be able to properly kinit. Fixing #2 may be done by adding the missing principal (kadmin/<kadmin server FQDN>@<realm>) to the MIT KDC. In future versions of Ambari, you will be able to configure what the kadmin service principal is. However for now, Ambari assumes it is kadmin/<kadmin server FQDN>@<realm>. If one of these solutions does not help, you should take a look at your ambari-server.log file and see if there are any interesting error messages posted that you can share here.

NiFi 1.1 is ancient. I would not recommend running that old stuff. These are all working: https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.1.1/bk_release-notes/content/ch_hdf_relnotes.html#repo-location You can download NiFi from: http://public-repo-1.hortonworks.com/HDF/3.1.1.0/nifi-1.5.0.3.1.1.0-35-bin.zip http://public-repo-1.hortonworks.com/HDF/3.1.1.0/nifi-1.5.0.3.1.1.0-35-bin.tar.gz

@scott powers As per Support Matrices HDF 3.1 is supported with Ubuntu16 as well as Ubuntu 14: https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.1.0/bk_support-matrices/content/ch_matrices-hdf.html So you can find the Ubuntu 16 RPMs adn repo here: https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.1.0/bk_release-notes/content/ch_hdf_relnotes.html#repo-location . For HDF 3.0 Looks like the stack is available but the doc does not have a direct link to it: https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.0.2/bk_release-notes/content/ch_hdf_relnotes.html#repo-location . So please try changing the URL and replace ubuntu14 with ubuntu16 as following: Example: https://s3.amazonaws.com/public-repo-1.hortonworks.com/HDF/ubuntu14/3.x/updates/3.0.2.0/HDF-3.0.2.0-ubuntu14-tars-tarball.tar.gz Notice i have replaced "ubuntu14" to "ubuntu16" in the above URL and it allowed me to download. https://s3.amazonaws.com/public-repo-1.hortonworks.com/HDF/ubuntu16/3.x/updates/3.0.2.0/HDF-3.0.2.0-ubuntu16-tars-tarball.tar.gz . Similarly for Mpack: https://s3.amazonaws.com/public-repo-1.hortonworks.com/HDF/ubuntu16/3.x/updates/3.0.2.0/tars/hdf_ambari_mp/hdf-ambari-mpack-3.0.2.0-76.tar.gz .
