即使我在创建表的过程中使用特定的压缩创建配置单元表（包括内部和外部），但在加载数据（插入到表选择中）时，配置单元会话压缩参数会覆盖在创建表的过程中设置的压缩值，如何避免这种情况？
表格创建method:1 with 快速压缩

create external table someschema.table1(
id int,
firstname string,
lastname string,
)
row format delimited 
fields terminated by ','
STORED AS INPUTFORMAT  'org.apache.hadoop.io.compress.SnappyCodec'
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
location '/user/cloudera/table1'

表格创建method:2 with bzip压缩

create external table hiveschema.table2(
id int,
firstname string,
lastname string)
row format delimited 
fields terminated by ','
stored as textfile
location '/user/cloudera/table2'
TBLPROPERTIES ("orc.compress"="BZIP")

会话参数在表级别重写压缩集

SET mapreduce.output.fileoutputformat.compress.codec=<some compression codec>
SET hive.exec.compress.output=true;
SET mapreduce.output.fileoutputformat.compress=true;
