> Impala can set the 'avro.schema.url' table property on any tables but can't unset it even if the table is not in AVRO format:
> {code:sql}
> create table mytbl(i int) stored as textfile;
> alter table mytbl set tblproperties('avro.schema.url'='hdfs:////test-warehouse/avro_schemas/functional/alltypes.json');
> alter table mytbl unset tblproperties('avro.schema.url');
> ERROR: AnalysisException: Unsetting the 'avro.schema.url' table property is not supported for Avro table.
> {code}
> Hive is able to do this without any errors.
