David Randolph commented on SQOOP-485:
--------------------------------------
I was just saying you should be able to define what is being imported using an
SQL query. In my view, this is basic functionality for a Hive import.
Regarding your other comments:
# Yes, we only get one chance to define the Hive table. Would it be updated
dynamically using the incremental feature?
# You are correct: the --append is superfluous in this context. But it does no
harm, as far as I can tell.
# -
# In my tests, this command does in fact add rows to the existing Hive tables.
I will be testing this further in the coming days.
Thanks,
Dave

> I can work around this immediate failure by specifying the --target-dir flag.
> This seems to do the right thing, but the sqoop command hangs. Also, use of
> --target-dir with --hive-import is discouraged in SQOOP-464.
> How can I use the --query flag to import into Hive?
