---------------------------------------
Summary: Unsetting the 'avro.schema.url' table property is not
supported for non-Avro tables
Key: IMPALA-12888
URL: https://issues.apache.org/jira/browse/IMPALA-12888
Project: IMPALA
Issue Type: Bug
Components: Catalog
Reporter: Quanlong Huang
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.
