By default Sqoop always create 4 Map task, we can create more. It equally divides the data into 4 different Map task and load it to the HDFS parallelly. The reason convert sqoop import command into MapRed because the map reduce can be internally executed in parallel manner to import data faster into hdfs.

All sqoop import export commands are Map-only Job because the only work is to fetching and loading.
