使用Sparksql的shell转换Oracle的例子

//1.创建表
create table AUTO_PAID_CASE_TMP_01
(
branch_company_code VARCHAR(25),
policy_no VARCHAR(60),
product_code_detail VARCHAR(24),
accident_month VARCHAR(20),
paid_amount Double,
paid_insured Double,
paid_alae Double,
paid_amount_retain Double,
paid_insured_retain Double,
paid_alae_retain Double,
paid_num_noncancel Double,
paid_num_zero Double,
paid_num_cancel Double,
paid_num_noncancel_detail Double,
paid_num_zero_detail Double,
paid_num_cancel_detail Double,
estimate_amount Double,
estimate_amount_retain Double,
os_num Double,
os_num_detail Double
)row format delimited fields terminated by ‘,’ ;

//2创建表
create table AUTO_DL1_BASE_PREMIUM_TMP01
(
branch_company_code VARCHAR(21),
policy_no VARCHAR(60),
department_group_code VARCHAR(18),
department_code VARCHAR(24),
product_type VARCHAR(24),
estimate_product_type VARCHAR(500),
business_require_system2 VARCHAR(500),
product_code VARCHAR(24),
product_code_detail VARCHAR(24),
inception_month VARCHAR(6),
inquire_month VARCHAR(6),
selling_channel_type VARCHAR(6),
policy_type VARCHAR(3),
policy_status VARCHAR(15),
party_type CHAR(1),
premium_amount Double,
premium_amount_static Double,
premium_amount_retain Double,
premium_amount_retain_static Double,
premium_amount_withtax Double,
exposure Double,
exposure_detail Double,
gep Double,
nep Double,
ee Double,
ee_detail Double,
gep_withtax Double,
actuarial_usage_code VARCHAR(50)
)row format delimited fields terminated by ‘,’ ;

//3.导入hive数据
load data local inpath ‘/room/data/haha.csv’ overwrite into table AUTO_PAID_CASE_TMP_01;
（load data local inpath ‘文件路径’ overwrite into table 表名，其中overwrite是覆盖，不是追加！

//加上下面这句是导入本地文件的语句csv“，”隔开的形式。
//insert overwrite local directory “/tmp/out/”
//row format delimited fields terminated by “,”

//4.这是创建查询结果表正确格式
create table query_result as
select

ps此次使用如下内存参数查询的指令:
./spark-sql –master yarn –driver-memory 4G –executor-memory 3G –num-executors 4

经过多次调优，现有机器条件下（三台内存，11G，8G，8G）下以及3T硬盘空间，能够达到的最好效果，数据源于保险行业真实数据，不方便透露，260万条数据与64万条数据的关联产生结果表，速度还是非常不错的。
