Sqoop錯誤使用Oracle錢包

sqoop import -D mapred.map.child.java.opts='-Doracle.net.tns_admin=. -Doracle.net.wallet_location=.' -files $HOME/wallet/cwallet.sso,$HOME/wallet/ewallet.p12,$HOME/wallet/sqlnet.ora,$HOME/wallet/tnsnames.ora --connect jdbc:oracle:thin:@TEST2 --table SQOOP_TEST

現在用這個sqoop命令來從Oracle數據庫數據，但在下面的錯誤結束從Oracle數據庫中獲取Sqoop錯誤使用Oracle錢包

ERROR manager.SqlManager: Error executing statement: java.sql.SQLRecoverableException: IO Error: Unknown host specified

我的錢包： 的tnsnames.ora

TEST2= (DESCRIPTION = 
    (ADDRESS_LIST = 
     (ADDRESS = (PROTOCOL = TCP)(HOST = <IP>)(PORT = 1521)) 
    ) 
    (CONNECT_DATA = (server=dedicated) 
     (SERVICE_NAME = HDPTEST) 
    ) )

錢包做工精細，

$sqlplus /@TEST2

請幫我找到我在哪裏錯了。

你有oraclepki.jar，osdt_core.jar和osdt_cert.jar在類路徑，也請檢查出更多的細節（第9頁）中的「SSL with JDBC」白皮書。此外，電子錢包位置可以指定爲tnsnames.ora的一部分，如下所示。

LISTENER = (ADDRESS_LIST= 
(ADDRESS=(PROTOCOL=tcps)(HOST=servername)(PORT=2484)) 
) WALLET_LOCATION=(SOURCE=(METHOD=FILE)(METHOD_DATA=(
DIRECTORY=/server/wallet/path))

）

出口HADOOP_OPTS = 「 - Doracle.net.tns_admin = -Doracle.net.wallet_location = 」 解決了這個問題。感謝您提及該文件，我使用相同的方式做了更多的工作。 – onlyvinish
