从oracle到hive的sqoop数据错误

我想从oracle到HDFS的sqoop数据。我正在使用sqoop来达到这个目的。我下载了ojdbc6.jar，并把它放在/usr/hdp/2.2.0.0-2041/sqoop/lib的路径中，并执行以下命令来检查我是否能够连接到oracle数据库。从oracle到hive的sqoop数据错误

sqoop list-databases --connect jdbc:oracle:thin:@hostname:port/service --username XXXX --password XXXX --verbose;

我收到以下错误。

是否因为授予权限而发生此错误？我是否需要授予任何权限？或者这是一个连接错误？

可以试试这个http://stackoverflow.com/questions/29418270/sqoop-getting-java-lang-nullpointerexception-when-trying-to-connect-to-oracle –

我围绕sqoop命令工作，发现了这个解决方案。它为我工作。我从cmd中ping出了主机名，发现了它正在ping的IP地址。我用sqadop执行命令中的ipaddress替换了主机名，它正在工作。
