Re: [geomesa-users] GeoMesa points not displayed on GeoServer...

[Jim Hughes <jnh5y@xxxxxxxx>]

Luca,

Sorry for the trouble.  Generally, whenever we see an 
AccumuloServerException, we have to go to the tablet server and check 
the tserver logs for more details.  Occasionally, the Accumulo monitor 
web ui will have sufficient details.

If you can pass along a stack trace from there, it will likely help 
quite a bit.

There is a big difference between a WFS/GeoJSON request and a WMS 
request: the former returns all the data while the latter asks for a 
projection of it.  WMS only needs the geometry, and that transformation 
is handled server-side.  With the logs, we'll be able to figure out if 
the problem is a known one addressed in the last two release candidates 
or if it still affects rc.7.

Other than that, it looks like you are running Accumulo as a stand-alone 
node.  One gotcha I have hit with that is not changing the machine names 
in the Accumulo config from 'localhost' to the something which will 
resolve via DNS for the client connecting to Accumulo.

Cheers,

Jim
