I am currently using Hortonworks Sandbox (downloaded on their website) and I would like to run sqoop to connect to my Oracle database and retrieve information.
The steps I have already done:
- Install sqoop -> OK
- Ping my db server -> OK
- Download Oracle driver ojdbc6.jar -> OK
- Put Oracle driver ojdbc6.jar in /usr/lib/sqoop/lib -> OK
- Run
sqoop import --connect "jdbc:oracle:thin:readonly/readonly@//unixatd:1521:P1AX" --table DUAL
-> OK
I receive the following message:
15/06/16 04:25:01 INFO sqoop.Sqoop: Running Sqoop version: 1.4.5.2.2.4.2-2
15/06/16 04:25:01 WARN sqoop.ConnFactory: Parameter --driver is set to an explicit driver however appropriate connection manager is not being set (via --connection-manager). Sqoop is going to fall back to org.apache.sqoop.manager.GenericJdbcManager. Please specify explicitly which connection manager should be used next time.

And from there, I just don't know what to do next. If you could give me information on things that I could check, that could be great.
Please check if oracle driver is available at:
SQOOP_HOME/lib
