Hi David,

Did you ensure that your tables are created in the same namespace that is configured for GeoMesa?

In the accumulo shell, you can check the configurations. You should see something like this (assuming you used the namespace 'geomesa'):

root@mycloud> config -f context.classpath
-----------+---------------------------------------------------------+----------------------------------------------------------------------
SCOPE      | NAME                                                    | VALUE
-----------+---------------------------------------------------------+----------------------------------------------------------------------
site       | general.vfs.context.classpath.geomesa ..................... |
system     |    @override .......................................... | hdfs://mycloud:54310/accumulo/classpath/geomesa/.*.jar

root@mycloud> config -ns geomesa -f classpath
-----------+---------------------------------------------------------+----------------------------------------------------------------------
SCOPE      | NAME                                                    | VALUE
-----------+---------------------------------------------------------+----------------------------------------------------------------------
default    | table.classpath.context ............................... |
namespace  |    @override .......................................... | geomesa
-----------+---------------------------------------------------------+----------------------------------------------------------------------

If the script isn't working quite right, you can also follow the manual steps for configuring the classpath as outlined in the docs:

http://www.geomesa.org/documentation/user/accumulo/install.html#manual-install

or

http://www.geomesa.org/documentation/user/accumulo/install.html#namespace-install

Thanks,

Emilio

All:

   All under accumulo 1.7.2 I have installed geomesa 1.3.1 using the setnamespace.sh script onto
hdfs.
I have upgraded the commons-vfs2 to version 2.1 on all nodes (the documentation said 1.7.2 should ship with 2.1 but it does not).
In addition to the below I am getting a lot of warnings about compactions and assignments running a long time.

   Getting the following error:
