Description
When creating a Hive external table with the Avro schema URL defined the result is a table that cannot be queried or droped:
create table hive.test.avro_test (
LOAD_DATE varchar,
ID varchar,
EMAIL varchar,
NAME varchar
)
with (
format = 'AVRO',
external_location = 'hdfs://hdfs/test/table1',
avro_schema_url = 'hdfs://hdfs/schema/table1.avsc'
);
All operations on the table produce the following error:
SQL Error [16777216]: Query failed (#20250804_105604_00015_upgzh): org.apache.hadoop.hive.metastore.SerDeStorageSchemaReader class not found
Once the table is created it can no longer be managed from Trino.

Research direction
Start with the SQL reproduction in the issue, using an external Hive table with format AVRO and avro_schema_url. Trace how the operator configures Trino and Hive for this table, then verify that the created table can be queried and dropped without the SerDeStorageSchemaReader class-not-found error.
