Hi Vinoth,

If you cannot use *any* connector, change “common.loader” to load correct jars 
will help.
If only your connector meets NoClassDefFound issue, it means your jars are not 
packaged with sqoop.war.

Subject: Install a new connector jar into sqoop2

Hey guys,

I am working on a connector which connects to a sharded mysql cluster as the 
source. I built out the connector jar with its sqoopconnector.properties.

And I tried to make sqoop pick up the jar a couple of ways

1) Add the path to the jar in "common.loader" property in catalina.properties: 
This gives a NoClassDefFound on the SqoopConnector.class since it is probably 
in tomcat's system loader, which may be referenceable by external libs.

2) Randomly placing the connector jar in shared/server loader, which also did 
not work.

Wound up adding the connector as a dependency in sqoop-server's pom and it 
worked. (sort of validates the theory in 1)

I am probably a tomcat noob, so please let me know if there is a cleaner way to 
do this or supported documentation .. Or if this is an open issue, happy to 
work on a patch..

Thanks
Vinoth
