Why sqoop picks up hsqldb driver jar when connect to mysql db?
sam liu 2013-08-06, 01:52
Hi Experts,

Under SQOOP/lib, I have both hsqldb driver jar file and mysql driver jar
file:
- lib/hsqldb-1.8.0.10.jar
- lib/mysql-connector-java-5.1.20-bin.jar

But, when I try to connect to mysql db using sqoop import tool, sqoop will
pick up hsqldb driver jar and returned following exception. Even if I add
'--connection-manager org.apache.sqoop.manager.MySQLManager' into the
command, this issue still exists. But, after I removed the hsqldb jar file
from lib folder, this issue does not exist any more.

Why? What's the correct method to invoke import tool to avoid such issue?
Thanks!
