If an import job fails, the partial data files gathered up to that point are automatically discarded by the MR framework. Export failure handling is done on a case-by-case basis by the underlying connector. For example, some connectors provide the option for using staging tables that get populated first before moving the data into the destination table. This mechanism will insulate the destination table from accidental corruption in case the job fails mid stream.
