Review request for Sqoop.
Bugs: SQOOP-2295
https://issues.apache.org/jira/browse/SQOOP-2295
Repository: sqoop-trunk
Description
-------
Currently, an existing dataset will throw an exception. This differs from
`--as-textfile`. 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. The patch has made the handling of
`--as-textfile` and `--as-parquetfile` consistent. (Note that `--as-avrofile`
is not supported, which can be supported similias as parquet in follow-up jira.
