Hi Whitney,

nope. i used this code scanned data from accumulo table. 

Thanks and Regards.

Also, are you doing this just to generate some fake data?  You definitely are going to want to use the approach I mentioned previously when it comes to generating simple features from the rows returned by Accumulo (i.e. for the part where you compute the convex hull).

Try something like this:

Hi Whitney,

i create AdapterStore using following code. but it give me an exception.

AdapterStore s = (AdapterStore) new FeatureDataAdapter(createPointFeatureType());

protected static SimpleFeatureType createPointFeatureType() {

final SimpleFeatureTypeBuilder builder = new SimpleFeatureTypeBuilder();

final AttributeTypeBuilder ab = new AttributeTypeBuilder();

builder.setName("Point");

builder.add(ab.binding(Geometry.class).nillable(false).buildDescriptor("geometry"));

builder.add(ab.binding(Date.class).nillable(true).buildDescriptor("TimeStamp"));

builder.add(ab.binding(Double.class).nillable(false).buildDescriptor("Latitude"));

builder.add(ab.binding(Double.class).nillable(false).buildDescriptor("Longitude"));

builder.add(ab.binding(String.class).nillable(true).buildDescriptor("TrajectoryID"));

builder.add(ab.binding(String.class).nillable(true).buildDescriptor("Comment"));

return builder.buildFeatureType();

}

Thanks and Regards.

For your particular situation, you need to use AccumuloRowId on the entries that are returned by your scan.  Using this you can get the data adapter id for each particular entry that you're processing.  Using that data adapter id, you can recall the data adapter using AdapterStore. 

Make sense?

Hi,

does any one know how to create DataAdapter instance for AccumuloUtils.decodeRow(key,value,adaptor,index)

Thanks and Regards.
