Qian Xu commented on SQOOP-2295:
--------------------------------

I've checked the user manual, the handling of HDFS and Hive are indeed 
different.

For HDFS, unless {{--append}} is specified, the job will fail when destination 
exists already.
For Hive, unless {{--create-hive-table}} is specified, the job will become 
append mode.

> Hive import with Parquet should append automatically
