Re: [geomesa-users] Upgrading problem for GeoMesa from 1.2.3 to 1.3.1 
Hi Takashi,
Actually I believe the error is due to specifying z2 instead of xz2, since z2 doesn't support non-point geometries. When we validate the enabled indices, we filter out ones that don't support the schema. In this case, that resulted in zero indices. I'll add an explicit check to prevent a schema without indices from being created. 

Thanks,

Emilio

Hi Takashi,
You are right that the XZ2 index would be appropriate for MultiLineStrings. However, I think the error you're seeing is a bug in our code. Can you try the following:
simpleFeatureType.getUserData().put("geomesa.indexes.enabled", "xz2:1:3"); 

Thanks,

Emilio

Hello,
We use GeoMesa1.2.3 "z2" index with MutiLineString(non-point geometries).
Perhaps does we need to use the GeoMesa 1.3.1 "xz2" index with MutiLineString?

Hello,
We tried to upgrade some system from GeoMesa 1.2.3 to 1.3.1, a error is occered.

It is seemed to be schema difinition issue, because
AbstractGeoMesaImporter.java:137 is executing
dataStore.createSchema(simpleFeatureType).

1. failed code
  protected SimpleFeatureType createSimpleFeatureType(
    String simpleFeatureTypeName) throws SchemaException {
   // list the attributes that constitute the feature type
   List<String> attributes = Lists.newArrayList(
    "*Where:MultiLineString:srid=4326", // the "*" denotes the default
geometry (used for indexing)
"RoadType:String" // you may have as many other attributes as you like... 
   );
   // create the bare simple-feature type
   String simpleFeatureTypeSchema = Joiner.on(",").join(attributes);
   SimpleFeatureType simpleFeatureType = SimpleFeatureTypes.createType(
     simpleFeatureTypeName, simpleFeatureTypeSchema);
simpleFeatureType.getUserData().put("geomesa.indexes.enabled", "z2");
   return simpleFeatureType;
  }

2. success code (uncommented withIndexes method, same error occurred)
  protected SimpleFeatureType createSimpleFeatureType(
    String simpleFeatureTypeName) throws SchemaException {
   final SimpleFeatureType simpleFeatureType = new SftBuilder().
     stringType("RoadType", false).
     multiLineString("Where", true).
     //withIndexes(ScalaConvetUtils.list("z2")).
     build(simpleFeatureTypeName);
   return simpleFeatureType;
  }

I don't understand the cause of this error at all.
Please advise me.


Thanks,

Takashi
