may help you . Sounds like you're trying to do something similar to slide 47 in this deck: http://www.slideshare.net/planetcassandra/escape-from-hadoop
The strategy Russell uses there is to use the spark mysql driver, no need to deal with Sqoop. You do have to add the dependency to your spark classpath for it to work. No need to go through a CQL table.

I wish this helpful for you Off the top of my head i recall you can specify --hive-table foo.tb
where foo is your hive database and tb is your hive table.
code :
sqoop import --connect jdbc:mysql://remote-ip/db --username xxx --password xxx --table tb --hive-import --hive-table foo.tb

fixed the issue. Will look into that further As mentioned in the sqoop documentation, you will not have to create any hive tables if you use the --hive-import argument in your command
example:
code :
sqoop import --connect jdbc:mysql://mysql_server:3306/db_name --username mysql_user --password mysql_pass --table table_name --hive-import

this will help You are using --hive-import, it will create hive table for you IF NOT EXISTS. It will create with Hive's default delimiter - fields terminated by : CTRL A and lines terminated by : \n
As per drill docs:
code :
sqoop import --connect jdbc:mysqll//localhost:3306/mysqldb \
--username user --password pwd --table mysqltbl \
--hive-import --hive-overwrite \
--hive-table hivedb.hivetbl -m 1 \
--hive-drop-import-delims \
--null-string '\\N' \
--null-non-string '\\N' \
sqoop import --connect jdbc:mysqll//localhost:3306/mysqldb \
--username user --password pwd --table mysqltbl \
--hive-import --hive-overwrite \
--hive-table hivedb.hivetbl -m 1 \
--hive-delims-replacement " " \
--null-string '\\N' \
--null-non-string '\\N' \

wish of those help Sqoop hive import will import data into HDFS first and then LOAD data into hive table.
In your case, your RDBMS table first migrated to /user/root/ and then loaded into Hive.
