hdfs TEXTFILE和PARQUET 格式推送数据到mysql
首先清理mysql目标表
sqoop eval -driver com.mysql.jdbc.Driver \
--connect jdbc:mysql://****:3306/basicdata?characterEncoding=UTF-8 \
--username root \
--password '****' \
--query "TRUNCATE TABLE DAILY_RATES"
textfile文件推送
sqoop export \
--driver com.mysql.jdbc.Driver \
--connect jdbc:mysql://****:3306/basicdata?characterEncoding=UTF-8 \
--table DAILY_RATES \
--username root \
--password '****' \
--input-null-string '\\N' \
--input-null-non-string '\\N' \
--fields-terminated-by '\001' \
--export-dir /DHDC/DWD/DWD_DAILY_RATES \
--m 1
PARQUET 文件推送(这里impala表示分区的，所以我现获取了最大的分区时间）
just_time=$(impala-shell -u hive -q 'select max(dt) from DHDC_DWD.DWD_STD_INV_ORG' -B)
echo $just_time
sqoop export --driver com.mysql.jdbc.Driver --connect jdbc:mysql://***:3306/basicdata?characterEncoding=UTF-8 --table STD_INV_ORG --username root --password '****' --columns "inv_org_id , inv_org_short_code,inv_org_cn,inv_org_en,ou_short_code_fk,date_from,date_to,create_user,create_time,update_user,update_time,dt" --input-null-string '\\N' --input-null-non-string '\\N' --fields-terminated-by '\001' --hcatalog-database DHDC_DWD --hcatalog-table DWD_STD_INV_ORG --hcatalog-partition-keys dt --hcatalog-partition-values $just_time --num-mappers 8
#!/bin/sh

source ~/.bash_profile
just_time=$(impala-shell -u hive -q 'select max(dt) from DHDC_DWD.DWD_DAILY_RATES' -B)
echo $just_time
sqoop export --driver com.mysql.jdbc.Driver --connect jdbc:mysql://***:3306/basicdata?characterEncoding=UTF-8 --table DAILY_RATES --username root --password '***' --columns "DAILY_RATES_ID,FROM_CURRENCY,TO_CURRENCY,CONVERSION_DATE,CONVERSION_TYPE,CONVERSION_RATE,INVERSE_CON_RATE ,CREATE_USER,CREATE_TIME,UPDATE_USER,UPDATE_TIME,DT" --input-null-string '\\N' --input-null-non-string '\\N' --fields-terminated-by '\001' --hcatalog-database DHDC_DWD --hcatalog-table DWD_DAILY_RATES --hcatalog-partition-keys dt --hcatalog-partition-values $just_time --num-mappers 8
[[ $? -eq 0 ]]||exit
#数据推送成功后，向版本里，写入当前版本
sqoop eval --connect jdbc:mysql://***:3306/basicdata?characterEncoding=UTF-8 --username root --password '***' --e "INSERT into VERSION(table_name,dt) values('DWD_DAILY_RATES','$just_time')"
