I'm curious what your job looks like. Could you provide the output of 'show link --all' and 'show job --all'?

Hmm maybe it is actually a null handling issue. Do you have issues importing data that don't have NULL values? Also, which database are you importing from?

Hey there,

Could you check your MapReduce task logs and your your container logs? There should be more information (a stack trace perhaps) describing what happened.
