Hi,

Are you getting this exception continuously for every load? Usually it
occurs when you try to load the data concurrently to the same table. So
please make sure that no other instance of carbon is running and data load
on the same table is not happening.
Check if any locks are created under system temp folder with
<detabasename>/<tablename>/lockfile, if it exists please delete.

Thanks & Regards,
Ravi
