Monitor finding wrong hostname
I'm running a single-node Accumulo 1.5.1 instance (using Hadoop 2.4) inside
Docker. Originally the configuration used 'namenode' as the hostname.
However, I have updated the process so that the hostname can be specified
during spinup.
I'm trying to start the instance using 'grail' as the hostname. As far as I
can see, the configuration is correct:
-bash-4.1# hostname
grail
-bash-4.1# hostname -f
grail
-bash-4.1# cat /etc/accumulo/conf/monitor
grail
Below is the exception I am seeing. Did I miss something?

Excellent!
Did this change also fix your gc problem?

It's working! I have four single-node accumulo instances running on my
laptop. I can visit the monitor page for each one. Changes in one instance
are isolated from the others. It takes less than 250 milliseconds to start
a new instance.

Thanks. After updating the accumulo-env.sh the process is pulling from
IPV4. But I have no idea why the hostname is being reported as 'namenode'
instead of 'grail'.

Actually, we do, and he isn't :)
https://github.com/medined/docker-builds/blob/master/accumulo/accumulo.conf/accumulo-env.sh
David, update your accumulo-env.sh. You also have cruft in there that is
no longer necessary (e.g. ACCUMULO_LOG_HOST)
