hive的表字段是4个string，一个int，一个timestamp，对应pg里面是4个text，一个integer，一个timestamp

sqoop export --connect jdbc:postgresql://192.168.136.151:5432/test --username postgres --password 'postgres' --table t_merchant_infocontent --export-dir /user/hive/warehouse/userdb.db/t_merchant_infocontent_for_mysql/* --input-fields-terminated-by '\t'
