Nope, grrrr.=C2=A0 I'm going to get the kick= start spec for our "minimized base" changed right NOW to include = host, dig, and nslookup!

Alex thanks for your help. My gut said it was reverse DNS lookup,= but when I asked I was told "it's all there."=C2=A0 Fixed no= w, thanks again!

Hi Alex,
I was told by the SysAdmin that yes, they are, as I requested that all ser= vers be in DNS with reverse lookup as well.

How can I test?=C2=A0 I would normally use nslookup, but our hard= ened servers do not include it ...

Greetin= gs folks,
I've just stood up a new Accumulo 1.4.2 cluster on a custo= mer's infrastructure where they are providing all core services such as= DNS, NTP, etc.

After starting the cluster for the first time and checking the mo= nitor, I find that all the Tablet Servers appear in the Server column as IP= addresses, not as hostnames, even though all configuration has been done u= sing hostnames only and DNS is in place and functioning.=C2=A0 No servers h= ave a custom /etc/hosts file with all hosts in it; all names are being reso= lved via DNS.

The very same base machine template works fine in another en= vironment, so I'm concerned it's something beyond my control (as in= DNS core services provided by the site).

Any ideas= ?

Many thanks in advance for your help.
