> Sqoop will fail if target directory already exists on HDFS. This can for example happen
after previously failed Sqoop import or in cases when users are re-importing the tables on
regular basis.
> Right now user is forced to remove the input directory manually prior re-executing Sqoop.
I think that it might be useful to add a new argument that would nuke the target directory
if it exists automatically.
> I believe that this feature will be safe to use as it will be turned off by default.
User will have to explicitly specify extra command line argument in order to remove any data.
