Hi Experts,
I built sqoop project to generate sqoop-1.4.3.bin__hadoop-1.0.0.tar.gz
using command:'ant -Dhadoopversion=100 tar'. Before that, I clean up my ivy
repository.
However, using the generated sqoop-1.4.4 project, I still encountered
IncompatibleClassChangeError as below. My command likes 'sqoop import
--connect jdbc:db2://hostname:50000/SAMPLE --table DB2ADMIN.DB2TEST_TBL
--username
user --password passwrd --target-dir /tmp/DB2TEST_TBL --split-by id'.
Any commnts? Thanks!
