Hadoop 使用sqoop将数据传输到hdfs时出错

我使用sqoop在hdfs和oracle之间传输数据，如下所示：

hadoop@jiogis-cluster-jiogis-master-001:~$ sqoop import --connect jdbc:oracle:gis-scan.ril.com/SAT --username=r4g_viewer --password=viewer_123 --table=R4G_OSP.ENODEB --hive-import  --hive-table=ENODEB --target-dir=user/hive/warehouse/proddb/JioCenterBoundary -- direct

当我使用如上所示的sqoop时，我得到如下所示的错误

您的jdbc连接字符串看起来不正确。你能用这种格式试试吗：

--connect jdbc:oracle:thin:@//hostname:port/servicename

在您的情况下，这可能是：

--connect jdbc:oracle:thin:@//gis-scan.ril.com:1521/SAT

---

您可能需要再次检查端口号是否正确，因为扫描侦听器可能不在默认的1521端口上。

当我尝试上述操作时，得到的结果如下16/05/16 06:11:28信息sqoop。sqoop:运行sqoop版本：1.4.6--表或--导入时需要查询。（或使用sqoop导入所有表。）
