Well, I'm not sure wtf is going on, but I added some sleeps to your
init.sh script (30seconds before starting ZooKeeper and before init'ing
Accumulo) and now things worked just fine.
I'm not seeing any Accumulo problems here, but rather the same Docker
absurdities I run into every time I try to use it :). I also just
upgrade to Docker 1.10.3 if that helps.

So, I got it running, and ran into the same problem you described.
The odd thing is that both the Accumulo Master and TabletServer seemed
to be... stuck. They both claimed to be running, but they were both hung
(unable to communicate). This ultimately caused the TabletServer to lose
its ZooKeeper lock (and why the Shell didn't think it was running).
I'm running into all sorts of docker issues ATM (trying to upgrade now,
hoping it will help), but I'd recommend trying to increase the amount of
heap for both the master and tserver from 128M to 256M in
/accumulo-1.7.1/conf/accumulo-env.sh (the -Xmx value).

Ok! Thanks, I'll look for that init.sh script.
We're not too... docker-savvy here yet :), but we can definitely help
out if we can find an automation script. Let me get back to you.

Hi Josh,
thanks for your answer.
Currently I haven't uploaded the Dockerfile... If you want I'll upload
it!
(But currently it only is an debian with ssh, rsync, jdk7, the
unzipped distributions of hadoop, zookeeper and accumulo, and the set
of environment variables)
Currently, and for testing, I start all things manually.
The steps I do is documented in /init.sh within the docker container.
I've enshured that dfs and zookeeper are up before starting accumulo.
Regards,
Sven

Betreff: Re: Accumulo 1.7.1 on Docker
Hi Sven,
I can't seem to find the source for your Docker image (nor am smart
enough to figure out how to extract it). Any chance you can point us to
that?
That said, I did run your image, and it looks like you didn't actually
start Hadoop, ZooKeeper, or Accumulo.
Our documentation treats Hadoop and ZooKeeper primarily as
prerequisites, so check their docs for good instructions.
For Accumulo -
Configuration:

Initialization:

Dear reader,
I'd like to create a docker image with accumulo 1.7.1.
I've install it from scratch with hadoop-2.7.2, zookeeper-3.4.8 and
accumulo-1.7.1.
I'm going though the installation and every time I'll end up like
that:
root@deebd8e29683:/# accumulo shell -u root
Password: ******
2016-03-13 13:18:31,627 [trace.DistributedTrace] INFO : SpanReceiver
org.apache.accumulo.tracer.ZooTraceClient was loaded successfully.
2016-03-13 13:20:31,955 [impl.ServerClient] WARN : There are no
tablet servers:
check that zookeeper and accumulo are running.
Anybody got an idea whats wrong? I have no idea anymore...
I'll currently share this docker image on docker hub.
If you want to try it you can simply start:
docker run -it themerius/accumulo /bin/bash
All binaries and configs are in there. In ./init.sh are my setup
steps.
Regards,
Sven
