--------------------------
a.sqoop create-hive-table --connect jdbc:oracle:thin:@192.168.31.222:1521:orcl --username shebaouser --password shebaouser --hive-table PEOPLE_BASE_INFO --table PEOPLE_BASE_INFO --fields-terminated-by '\t'

b.hive修改列類型，double格式在kettl中沒法支持，需要修改爲string
alter table org_base_info change id舊列名 id新列名 string comment 'id註釋' first;

c.sqoop導入數據
sqoop import --connect jdbc:oracle:thin:@192.168.31.222:1521:orcl --username shebaouser --password shebaouser --table PEOPLE_PAY_INFO --num-mappers 2  --delete-target-dir --hive-import --hive-database default --hive-table PEOPLE_PAY_INFO --hive-overwrite --fields-terminated-by '\t'

如果沒有主鍵，則需要指定--m 1,一個mapper

空值處理--null-string '\\N' --null-non-string '\\N'

d.hive 從hdfs中導入表數據

load data inpath '/user/hive/warehouse/shebaouser/org_base_info.txt' into table org_base_info;

e.如果hive執行where語句半天都沒有結果，一直處於hang的狀態時，檢查各個組件的配置，如果是CDH，檢查配置問題，糾正配置問題後就可以正常執行了。

------------------------------------------

spoon轉換設置不傳對應的頭，分隔符使用\t

創建一個hive表，

create table 。。。。 ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';

如果出現用戶權限的問題$ sudo -u hive sqoop import ...
