建议同步写方式方式多一种选择，可考虑写到hive orc 表，性能方面会有所提升，现在是直接写到文本，例如：
sqoop import --connect jdbc:oracle --username xxx --password xxx --table
xxx.xxx --hcatalog-databse xxx --hcatalog-table xx
--drop-and-create-hcatalog-table --hcatalog-storage-stanza 'stored as orc
tblproperties ("orc.compress"="SNAPPY","transactional"="false")' --m 1
