sqoop与PG库导入导出数据

导入数据到Hive

sqoop import --connect jdbc:postgresql://172.66.6.666/radar5g4h --username postgres --password 1234 \
--query " select antenna_model,type,theta,gain from wcnos_antenna_beam where \$CONDITIONS " \
--target-dir table1 --delete-target-dir \
--hive-import --hive-database ott --hive-table table1 \
--null-string '\\N' \
--null-non-string '\\N' \
--fields-terminated-by "," \
-m 1

 

导出数据到PG库

sqoop export --connect jdbc:postgresql://172.66.6.666/radar5g4h --username postgres --password 1234 \
--table table1 \
--export-dir /user/hive/warehouse/ott.db/table1 \
--fields-terminated-by ',' \
--m 1 \
--input-null-string '\\N' --input-null-non-string '\\N'

sqoop到导入数据到PG库时，会通过select * from table 来确定表是否存在，如果不存在则抛出错误。
