Connecting to a kerberized HBase 2 instance
Can the 1.1.2 client connect to a kerberized HBase 2 instance? We're stuck
on NiFi 1.8.0 for now and someone upgraded us to HBase 2.0 for our new VMs.
I can backport the NAR, but wanted to check. Getting a lot of
ConnectionLoss errors from ZooKeeper looking for /hbase-secure and other
things from the new installation and am trying to limit the range of
possible problems here.
Thanks,
Mike

For us, we did a major HDP 2.6 -> 3.0 upgrade. This upgraded HBase to
2.x, and I was pleasantly surprised to find our NiFi flows (using
HBase_1_1_2_ClientService) just worked with their previous settings.

After some fighting, we got straight down to an issue with it throwing
MasterNotRunningException (or whatever it's called), indicating it couldn't
find the master on the configured host and port. So at this point, I assume
it's a security group issue.
Thanks,
Mike

Yes, James's statement is what I believe to be true as well.

That combo works for me. AIUI, the data API is compatible but the
management API (table creation etc) isn't.
