I installed NIFI in two separate location nifi and nifi2 with different ports - one without kerberized ZK and one with kerberized ZK. However, both web UI (8080 and 9080) see the same nifi flow graphs. How could they share the same internal database such as H2?

Yes. However, we use adkeytab from Centrify. Here is a blog on this (he used adkeytab to add spn and kutil to merge with no detailed steps). https://www.centrify.com/activate/cmz3c60glnnmc1tnlwnv0srcpkfct5p9/

Thanks Sunile. We got that already. This is for adding two principals in the same key tab using AD, not MIT kdc.

Anyone knows how to do with AD adkeytab command? https://community.hortonworks.com/articles/35019/oozie-ha-configuration-with-kerberos.html step 8 requires to add more than more principals in the same keytab.

Do you mean that each nifi user should have his/her own instance? There could be too many. Also is there any way to specify multiple instances per host?

Currently HDF 1.2 is running as user root. I am using HDP 2.3.2 so NIFI is not part of Ambari controlled list. Since it is run as root, getHDFS or putHDFS processor uses a user keytab. How could I prevent a user A to create a processor to use user B's keytab? In HDP 2.4 or later, do we have NIFI service user ID provisioned?

There are three directories to be on NFS mount. Conf directory should not take much space. I checked retry directory and it was empty. Will it be automatically cleaned up? I checked graph storage and I had under 1 mb since I have only a few feeds. Will it keep growing as I add more feeds? How to get a good estimation on this? https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.2/bk_data_governance/content/ch_appendix_data_gov_config_ha.html
*.retry.recorder.path: This location should be an NFS-mounted directory that is owned by Falcon, and with permissions set to 755. *.falcon.graph.storage.directory: This location should also be an NFS-mounted directory that is owned by Falcon, and with permissions set to 755. Falcon conf directory: The default location of this directory is <falcon_home>/conf, which is symbolically linked to/etc/falcon/conf. This directory must point to an NFS-mounted directory to ensure that the changes made on the primary Falcon server are populated to the back-up server.

I don't think it works. Tried with /hdfsDataLocation only, retention doesn't work.
