sqoop从msyq导入数据到hive，自定建表
sqoop import --connect ‘jdbc:mysql://xxx.xxx.xxx.xx:3306/database?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL‘ --username root--password 123456 --table student_info --hive-import --hive-drop-import-delims --create-hive-table --hive-database lods --hive-table lods_source_dxxbs_student_info --fields-terminated-by "\001" --lines-terminated-by "\n" -m 1
注意：一定要添加 --hive-drop-import-delims 否则，mysql字段中包含\r\n会导致数据错位
sqoop导入数据到hive，覆盖hive已有数据
/data/software/sqoop-1.4.7/bin/sqoop import --connect "jdbc:mysql://xxx.xxx.xxx.xxx:3306/database?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL" --username root --password 123456 --table student_info --fields-terminated-by "\001" --hive-drop-import-delims --lines-terminated-by "\n" --hive-import --hive-overwrite --hive-database lods -–create-hive-table --hive-table lods_source_dxxbs_student_info -m 1
