Re: [geomesa-users] Questions regarding ingestion in geomesa

Hi Vaibhav,

In general, GeoMesa allows you to leave most attributes blank (however you must always include the default geometry). I don't think that the exception you're getting is coming from GeoMesa - I did a quick search for that message and don't see it anywhere. Can you provide more of a stack trace, or the code you're using?

One thing that might be affecting you is how you create the simple feature type. In order to use hints like 'index=full', you need to use one of the GeoMesa simple feature type helpers - either SimpleFeatureTypes.createType, the SftBuilder or a typesafe config file. If not, then the index hints you are setting will probably get dropped. In addition, simple feature types have 'nullable' hints on each attribute descriptor. In GeoMesa, we allow anything to be null (except the primary geometry), so we ignore those settings. However, if you're using GeoTools classes it may be trying to validate your attribute values at some point.

Thanks,

Emilio
