Hello,

I sent a message last week about 1 tablet server not showing up on one of my 4 node clusters running Accumulo.  After inspecting some of the log files, etc.  it appears that the tablet server on my node 2 is starting on localhost instead of starting on the actual IP of the node.  Any ideas what might cause this?

Thanks,
Duane

I assume you mean it's listening on 127.0.0.1 on that node? Are you using
bin/start-all.sh to launch your cluster? I would guess this is a DNS setup
issue on that one machine. Maybe something like the domainname not being
set? When you run "hostname" on that machine, do you get a similar format
to what you see on the other nodes?

Adam,
In my   tserver_*.debug.log     file, it says:
[tabletserver.TabletServer] INFO : Tablet server starting on 127.0.0.1

On all of the other nodes, in place of the 127.0.0.1, the machine's actual IP address appears.  I am using bin/start-all.sh on the name node to launch the cluster.  When I run hostname, I do see the correct name and it is formatted the same way as the other machines.  I'll look into the DNS setup to make sure everything else seems correct.

Thanks for your help,
Duane

I experienced this once on a cluster, but I didn't have the time to debug
it. Some questions which may be able to help shed some light on this-
1. How are you starting this node's tserver?
2. What are you using for this node in the slaves file, if you're using it.
3. Is that node using the same DNS servers as the others?
4. Are you using your HOST file to identify nodes?

Make sure you don't have the actual server hostname listed in the same line
at 127.0.0.1 localhost in /etc/hosts.

Jason,

That was my problem.  In our rush to get the cloud up, we forgot the entry in /etc/hosts.  Thanks for catching this!

Make sure you don't have the actual server hostname listed in the same line at 127.0.0.1 localhost in /etc/hosts.
