kettle cluster:  master01, slave01, slave02

it's successful to testing while i create new connection for impala or hive, and it can be success while i use local mode or choose the server which i start spoon.sh  to extract data from impala. so, i think there is no any impala driver issue should be happened.

my question is : why the job failed and show the errors like no suitable driver while i apply transformation or job in cluster mode or choose the server which it's not the location to start spoon.sh ?

who can give some advises for this issue?  thank you .
