2. 创建 hive 临时表
CREATE EXTERNAL TABLE if not exists sensitop.equd_json_tmp (
retCode string,
retMsg string,
data array<struct<
secID: string,
tradeDate: date,
ticker: string,
secShortName: string,
exchangeCD: string,
preClosePrice: double,
actPreClosePrice: double,
openPrice: double,
highestPrice: double,
lowestPrice: double,
closePrice: double,
turnoverVol: double,
turnoverValue: double,
dealAmount: int,
turnoverRate: double,
accumAdjFactor: double,
negMarketValue: double,
marketValue: double,
PE: double,
PE1: double,
PB: double,
isOpen: int>>)
ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'
LOCATION 'hdfs://hdfs1.wdp:8020/sensitop/finance/equd';
3. 创建 hive 表
需要把上面表里数组里的数据一条一条放入这个表：
CREATE TABLE if not exists sensitop.equd_h(
secID string,
ticker string,
secShortName string,
exchangeCD string,
tradeDate date,
preClosePrice double,
actPreClosePrice double,
openPrice double,
highestPrice double,
lowestPrice double,
closePrice double,
turnoverVol double,
turnoverValue double,
dealAmount int,
turnoverRate double,
accumAdjFactor double,
negMarketValue double,
marketValue double,
PE double,
PE1 double,
PB double,
isOpen int)
partitioned by (year string)
ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'
然后新建一个最张表
CREATE TABLE if not exists sensitop.equd(
secID string,
ticker string,
secShortName string,
exchangeCD string,
tradeDate date,
preClosePrice double,
actPreClosePrice double,
openPrice double,
highestPrice double,
lowestPrice double,
closePrice double,
turnoverVol double,
turnoverValue double,
dealAmount int,
turnoverRate double,
accumAdjFactor double,
negMarketValue double,
marketValue double,
PE double,
PE1 double,
PB double,
isOpen int)
partitioned by (year string)
注意：这里的字段顺序和上面临时表的顺序要一致。
4. 用 Partition 更新数据
insert overwrite table sensitop.equd_tmp
partition (year='2016')
select b.dt.secID,
b.dt.ticker,
b.dt.secShortName,
b.dt.exchangeCD,
b.dt.tradeDate,
b.dt.preClosePrice,
b.dt.actPreClosePrice,
b.dt.openPrice,
b.dt.highestPrice,
b.dt.lowestPrice,
b.dt.closePrice,
b.dt.turnoverVol,
b.dt.turnoverValue,
b.dt.dealAmount,
b.dt.turnoverRate,
b.dt.accumAdjFactor,
b.dt.negMarketValue,
b.dt.marketValue,
b.dt.PE,
b.dt.PE1,
b.dt.PB,
b.dt.isOpen
from sensitop.equd_json_tmp LATERAL VIEW explode(equd_json_tmp.data) b AS dt
where dt.tradedate >= '2016-01-01' and dt.tradedate <= '2016-12-31';
insert overwrite table sensitop.equd
partition (year='2016')
select secID,
ticker,
secShortName,
exchangeCD,
tradeDate,
preClosePrice,
actPreClosePrice,
openPrice,
highestPrice,
lowestPrice,
closePrice,
turnoverVol,
turnoverValue,
dealAmount,
turnoverRate,
accumAdjFactor,
negMarketValue,
marketValue,
PE,
PE1,
PB,
isOpen
from sensitop.equd_tmp dt
where year = '2016';
5. 用nifi实现动态插入数据
这里有二个分支，左边一个是每天20：00更新当年的partion； 右边一个是更新1990 到 2015 年的数据，而且只需要更新一次。
insert overwrite table sensitop.equd_h
partition (year='${year}')
select b.dt.secID,
b.dt.ticker,
b.dt.secShortName,
b.dt.exchangeCD,
b.dt.tradeDate,
b.dt.preClosePrice,
b.dt.actPreClosePrice,
b.dt.openPrice,
b.dt.highestPrice,
b.dt.lowestPrice,
b.dt.closePrice,
b.dt.turnoverVol,
b.dt.turnoverValue,
b.dt.dealAmount,
b.dt.turnoverRate,
b.dt.accumAdjFactor,
b.dt.negMarketValue,
b.dt.marketValue,
b.dt.PE,
b.dt.PE1,
b.dt.PB,
b.dt.isOpen
from sensitop.equd_json_tmp LATERAL VIEW explode(equd_json_tmp.data) b AS dt
where dt.tradedate >= '${year}-01-01' and dt.tradedate <= '${year}-12-31'
insert overwrite table sensitop.equd
partition (year='${year}')
select secID,
ticker,
secShortName,
exchangeCD,
tradeDate,
preClosePrice,
actPreClosePrice,
openPrice,
highestPrice,
lowestPrice,
closePrice,
turnoverVol,
turnoverValue,
dealAmount,
turnoverRate,
accumAdjFactor,
negMarketValue,
marketValue,
PE,
PE1,
PB,
isOpen
from sensitop.equd_tmp dt
where year = '${year}'
