As you are basically getting the error:

Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.apache.derby.jdbc.AutoloadedDriver40

.

So can you please confirm if you have placed the Driver JAR which contains the class "org.apache.derby.jdbc.AutoloadedDriver40" inside the $SQOOP_HOME/libdirectory of your Sqoop installation.

As described in : https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.5/bk_data-movement-and-integration/content/ap...

May be you can download it from Derby site ... or just for testing you can try this:

Should i place this jar inside $SQOOP_HOME/lib or inside $HIVE_HOME/lib?

But I have placed the mysql jdbc jar inside the $SQOOP_HOME/lib... All the derby jars are placed inside the $HIVE_HOME/lib
