Using Sqoop to import data from MySQL to Hive

Question

I am using Sqoop (version 1.4.4) to import data from MySQL to Hive. The data will be a subset of one of tables, i.e. few columns from a table. Is it necessary to create table in

Answer 1

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:

sqoop import --connect jdbc:mysql://mysql_server:3306/db_name --username mysql_user --password mysql_pass --table table_name --hive-import

Also... consider the --hive-overwrite argument if you want to schedule a full data import, on a daily base for example
