Use sqoop to import Oracle table to HFDS. Oracle JDBC jar is not installed to $SQOOP_HOME/lib

New Contributor

I want to run sqoop to import Oracle to HDFS. Our default CDH deployment does not have Oracle JDBC driver. So I downloaded the driver and saved  to my home directory on CDH proxy server. I tried to run sqoop using --libjars to use the driver, but it was not working. Can you advise how to get this working?

 

sqoop import  --libjars <my dir>/ojdbc6.jar --connect jdbc:oracle:thin:@//<host>:8526/<SID> --table pstobj2 --username <username> --password <pass> --target-dir <dir path>/table_name

Re: Use sqoop to import Oracle table to HFDS. Oracle JDBC jar is not installed to $SQOOP_HOME/lib

Cloudera Employee

If you have installed sqoop using parcels, you will need to set the HADOOP_CLASSPATH in your environment to specify the JDBC driver. 

You can set this in the client's configuration file: /etc/sqoop/conf/sqoop-env.sh

JDBC Drivers should be downloaded and copied into directory /usr/lib/sqoop/lib as is described in the installation gudie:

To what value should you set the HADOOP_CLASSPATH?

were you able to solve the issue? If same issue persists, please check the permission

 

it should be sqoop:sqoop 755 and placed in sqoop lib.

 

In case of parcels, /var/lib/sqoop/

 

In case of packages, /usr/lib/sqoop/lib/
