[geomesa-users] Use geomesa processes with Spark

["GRISOT, REMI" <remi.grisot@xxxxxxxx>]

Hello,

I have position history for some cabs and I would like to find the
points of interests where they stopped.
To achieve this, I used geomesa processes (query and knn): first, I keep
only features when speed is 0 (query process) and then foreach feature,
I do a knn-search with k=1 and max radius = 500m.
This works fine, however I would like to parallelize this over a spark
cluster. So I converted my FeatureCollection into a spark RDD and tried
to apply filter and knn on each row. But I got an
NotSerializableException because AccumuloFeatureCollection is not
serializable.

I saw that some geospatial functions are available in spark using jts
module, however I could not find KNN.
Is there a way to use geomesa processes with spark?

Thank you!
