OJDBC 驱动程序中的 Cloudera QuickStart VM Sqoop 错误

Question

我安装了 Cloudera QuickStart VM 5.13。我正在使用 Sqoop。我尝试执行下一个命令：

[cloudera@quickstart ~]$ sqoop list-tables --connect jdbc:oracle:thin:@localhost:1521:xe --username Guest1 --password G147

然后我有错误：

Warning: /usr/lib/sqoop/../accumulo does not exist! Accumulo imports will fail.
Please set $ACCUMULO_HOME to the root of your Accumulo installation.

我认为 Cloudera 没有 OJBDC 驱动程序。

我需要做什么？我必须在哪里安装 Oracle OJDBC 驱动程序？它叫什么名字？

研究:

1. 我已将 ojdbc6.jar 放在下一个目录中：

sudo cp /home/cloudera/Downloads/ojdbc6.jar /var/lib/sqoop/ojdbc6.jar
sudo cp /home/cloudera/Downloads/ojdbc6.jar /var/lib/sqoop2/ojdbc6.jar
sudo cp /home/cloudera/Downloads/ojdbc6.jar /var/lib/oozie/ojdbc6.jar
sudo cp /home/cloudera/Downloads/ojdbc6.jar /usr/share/java/ojdbc6.jar
sudo cp /home/cloudera/Downloads/ojdbc6.jar /usr/share/java/ojdbc6.jar
sudo cp /home/cloudera/Downloads/ojdbc6.jar /usr/share/cmf/common_jars/ojdbc6.jar
sudo cp /home/cloudera/Downloads/ojdbc6.jar /usr/share/cmf/cloudera-scm-telepub/jars/ojdbc6.jar
sudo cp /home/cloudera/Downloads/ojdbc6.jar /usr/lib/sentry/lib/ojdbc6.jar
sudo cp /home/cloudera/Downloads/ojdbc6.jar /usr/lib/hive/lib/ojdbc6.jar
sudo cp /home/cloudera/Downloads/ojdbc6.jar /usr/share/java/ojdbc6.jar

同样的错误。

Answer 1

安装JDK 1.7（或需要）并设置系统变量（JAVA_HOME、ORACLE_HOME, ORACLE_SID) 并复制 jar (/var/lib/sqoop/ojdbc6.jar)。例如：

export JAVA_HOME=/usr/java/jdk1.7.0_80/
export ORACLE_HOME=/opt/oracle/product/18c/dbhomeXE/
export ORACLE_SID=XE
