[geomesa-users] Errors while running KNearestNeighborSearch
|
Hello,
I'm trying to run KNearestNeighborSearch in geomesa-process
(https://github.com/locationtech/geomesa/tree/master/geomesa-process)
using "WPS request builder" on GeoServer but I got below error:
Request: getServiceInfo

Is there any idea to solve this problem?
By the way, I tried with Point2Point query and it worked without any
error. So I don't think it is a problem of accumulo configuration.
Thank you in advance.
