Subject reg: Json to Parquet
Date Fri, 08 Mar 2019 09:55:37 GMT
Hi,

I have a CTAS query that converts JSON to Parquet format and encounter this
error sometimes

 (org.apache.parquet.schema.InvalidSchemaException) Cannot write a schema
with an empty group: optional group address

I guess this happens when drill encounters a field like "address" : {}
(empty object)

Is there a way to handle this ?

Thanks,
-Dweep
