主要是对CDH6.0.1平台，Hive的压缩进行设置。 采用ORC+Snappy压缩是比较常用的格式，CDH6已经自动部署了Snappy压缩。 Hive表启用压缩 set hive.exec.compress.output=true; CREATE TABLE `virtual_payment_cp` ( `ID` bigint, `DEVICE_CODE` string COMMENT 'xx', `LOGIN_ACCOUNT` string COMMENT 'xx', `AMOUNT` decimal(11,2) COMMENT 'xx', `PAY_RESULT` int COMMENT 'xx', `CP_GAME_ID` bigint COMMENT 'xx' ) PARTITIONED BY(`DATE` STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t' STORED AS orc tblproperties ("orc.compress"="SNAPPY"); Map阶段启用压缩 CDH -> YARN ->配置 -> mapred-site.xml -> mapred-site.xml 的 MapReduce 客户端高级配置代码段（安全阀），添加 <property><name>mapreduce.map
