Caught up with Russ in IRC -- without trying to reproduce it by hand,
this strongly looks like an issue in Ambari (preventing these characters).
FYI, Billie.

Hi, folks,
I'm following the instructions in the 1.7 user manual to set up Kerberos
impersonation. I'm using Ambari 2.1.2.1 to specify the configuration in
accumulo-site.xml.
If I understand the manual correctly, I need to define a property key of
the form: instance.rpc.sasl.impersonation.username/[email protected].
The value should be a CSV list of kerberos principals.
The problem is that Ambari will reject a property key with the
characters "@" or "/". Is Ambari being overly restrictive or have I
misunderstood the user manual? Is there any workaround other than
manually editing accumulo-site.xml (which I think will be overwritten as
soon as Ambari discovers that it's out-of-sync)?
Thanks,
-Russ
