> In local catalog mode we always try to load the Avro schema if the table property 'avro.schema.url' is present:
> https://github.com/apache/impala/blob/80fc49abe6c574f8d6bea8bb56ff4917f6281a41/fe/src/main/java/org/apache/impala/catalog/local/LocalFsTable.java#L142
> This makes tables unloadable if the value of this table property is invalid. Even if the actual table doesn't have any Avro partitions.
> This is a regression from legacy catalog mode where we only tried to load the Avro schema if the table actually had Avro data:
> https://github.com/apache/impala/blob/80fc49abe6c574f8d6bea8bb56ff4917f6281a41/fe/src/main/java/org/apache/impala/catalog/HdfsTable.java#L1758
