Question

尝试使用SSL连接从ORACLE DB导入（SQOOP）表数据到HDFS。

我使用的Sqoop命令如下，

sqoop import -Djavax.net.ssl.trustStore = / app / Wallets / client_wallet / ewallet.p12 -Djavax.net.ssl.trustStoreType = PKCS12 -Djavax.net.ssl.trustStorePassword = WalletPasswd123 --connect jdbc：oracle ：thin：@testssl --username test --password test --table APP_INSTANCE

ERROR：

的tnsnames.ora：

testssl =   (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCPS)(HOST = IP )(PORT = 2484))
    (CONNECT_DATA = (SERVER = dedicated)(SERVICE_NAME = ORACL)))

sqlnet.ora中：

WALLET_LOCATION=(SOURCE=(METHOD=FILE)  
      (METHOD_DATA=(DIRECTORY=/app/Wallets/client_wallet)))
SQLNET.AUTHENTICATION_SERVICES = (tcps)
SSL_CIPHER_SUITES = (SSL_RSA_WITH_AES_128_CBC_SHA,SSL_DH_anon_WITH_3DES_EDE_CBC_SHA)
SSL_CLIENT_AUTHENTICATION = FALSE

尝试使用SQLPLUS：

$ sqlplus64 neon_main/bullet@testssl

SQL>

这很好用。但不使用JDBC。

请指出我哪里错了。？

Answer 1

由于您使用的是TNS名称别名，因此应明确传递-Doracle.net.tns_admin =。此外，JDBC thin不会读取文件sqlnet.ora。因此，需要将这些属性显式传递为连接级属性。

查看SSL with JDBC whitepaper了解详情。
