Hello,
I'm running Accumulo 1.5.2, trying to test out the GeoMesa
<http://www.geomesa.org/2014/05/28/geomesa-quickstart/> family of
spatio-temporal iterators using their quickstart demonstration tool. I
think I'm not making progress due to my Accumulo setup, though, so can
someone validate that all looks good from here?
start-all.sh output:
hduser@accumulo:~$ $ACCUMULO_HOME/bin/start-all.sh
Starting monitor on localhost
Starting tablet servers .... done

I do believe my HDFS is set up correctly:
hduser@accumulo:/home/ubuntu/geomesa-quickstart$ hadoop fs -ls /accumulo

However, when I check the Accumulo monitor logs, I see these errors
post-startup:

I don't really understand - I started accumulo as the hduser, which is the
same user that has access to the HDFS directory /accumulo/recovery, and it
looks like the directory was created actually, except for the last
directory (part-r-0000):
hduser@accumulo:~$ hadoop fs -ls /accumulo0/recovery/
Found 1 items
drwxr-xr-x - hduser supergroup 0 2015-01-05 22:11
/accumulo/recovery/87fb7aac-0274-4aea-8014-9d53dbbdfbbc
I'm not out of physical disk space:
hduser@accumulo:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda1 1008G 8.5G 959G 1% /
What could be going on here? Any ideas on something simple I could have
missed?
Thanks,
Mike
