我使用sqoop1.4.5-cdh5.4.2和postgresql。
如果sqoop直接连接到数据库-好的。但是我需要使用sqoop而不是pgbouncer,我对此有问题。
在pgbouncer中,您不能在事务模式下执行准备语句。
... connect命令:
sqoop import \
--connect "$db_name" \
--username "$db_user" \
--password "$db_pass" \
--direct \
--hive-import \
--hive-table "$hive_schema.$t" \
--hive-overwrite \
--num-mappers 10 \
--fetch-size 100000 \
--split-by "object_id" \
--target-dir "/user/$hive_schema/$t" \
--table "$t"
... 和错误:
