У меня есть таблица Hive, которую я хочу перезаписать, используя Insert Overwrite, пример запроса ниже
spark.sql("INSERT OVERWRITE TABLE my_database.my_table VALUES (221221, 'DUMMY_Record_Pav', 21233, 'SPACE')")
--Show create Table
CREATE TABLE `my_database.my_table`(
`player_id` string,
`player_type` string,
`position_id` string,
`position_location` string)
ROW FORMAT SERDE
'org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe'
WITH SERDEPROPERTIES (
'path'='hdfs://path/hive/data/my_database.db/my_table')
STORED AS INPUTFORMAT
'org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat'
OUTPUTFORMAT
'org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat'

Я могу переписать аналогичную таблицу, в которой отсутствуют свойства SerdeProperties, как показано ниже:
WITH SERDEPROPERTIES (
'path'='hdfs://path/hive/data/my_database.db/my_table')
Есть ли способ удалить SerdeProperties для таблицы?
Я пытался установив путь к '', как показано ниже, но Spark Sql завершился неудачно с ошибкой пустого пути.
ALTER TABLE my_database.my_table SET SERDEPROPERTIES('path'='');
Удаление SerdeProperies поможет выполнить запрос Spark SQL.
