David Randolph edited comment on SQOOP-485 at 5/25/12 7:00 AM:
---------------------------------------------------------------
I have confirmed that one can add rows to Hive tables that already contain rows
with a command like this:
{noformat}
hive -e "load data inpath '/user/me/fact/day5' into table fact"
{noformat}
The pre-existing data are still visible in Hive.
Note that this is not really material to the issue raised here. This issue is
raised to remove the apparent incompatibility of the --hive-import and --query
flags. These flags should be compatible.
Thanks.

> This seems to do the right thing, but the sqoop command hangs. Also, use of
