我有avsc文件，我试图创建表使用如下，但得到错误。

CREATE TABLE doctors ROW FORMAT
SERDE 'org.apache.hadoop.hive.serde2.avro.AvroSerDe'
STORED AS
INPUTFORMAT 'org.apache.hadoop.hive.ql.io.avro.AvroContainerInputFormat'
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.avro.AvroContainerOutputFormat'    
TBLPROPERTIES ('avro.schema.literal'='{
"namespace": "ly.stealth.xmlavro",
"types": [     {
   "name": "Attribute",        "type": "record",
   "fields": [
       {"name": "name", "type": "string"},
       {"name": "value", "type": "string" }
   ]
},     {
 "name": "Element",
 "type": "record",      "fields": [
     {"name": "name", "type": "string"},
     {"name": "attributes", "type":   {"type": "array", "items": "Attribute"}},        
{"name": "children", "type": {"type": "array", "items": ["Element", "string"]} }
 ]
 }
]
}
');

错误如下：
