Jarek Jarcec Cecho commented on SQOOP-489:
------------------------------------------

I believe that adjusting generated "Create table" statement is only half of the 
job. We also need to stop importing those columns, because otherwise we would 
end up with different number of columns in imported file and in hive which 
might lead to a huge confusion on user side.

> Cannot define partition keys for Hive tables created through Sqoop

>                 Key: SQOOP-489
>                 URL: https://issues.apache.org/jira/browse/SQOOP-489
>             Project: Sqoop
>          Issue Type: Bug
>    Affects Versions: 1.4.1-incubating
>            Reporter: Kathleen Ting
>
> By enabling the table option, Sqoop includes every column in the table in the 
> create table query, and by enabling the hive-partition-key option, Sqoop 
> blindly appends the "partitioned by" clause. Now if you specify one of 
> columns in the table in the hive-partition-key, this will cause a syntax 
> error in Hive.
> For example, if we have a table 'FOO' that has columns 'I' and 'J':
> sqoop create-hive-table --table FOO ...
> will generate the following Hive query:
> CREATE TABLE IF NOT EXISTS `FOO` ( `I` STRING, `J` STRING)
> Now if we add "--hive-partition-key I" to the command, Sqoop generates the 
> following query:
> CREATE TABLE IF NOT EXISTS `FOO` ( `I` STRING, `J` STRING) PARTITIONED BY (I 
> STRING)
> The problem is that since 'I' is defined twice (once in CRATE TABLE and once 
> in PARTITIONED BY), this is a syntax error in Hive.
> This correct query would be something like:
> CREATE TABLE IF NOT EXISTS `FOO` (`J` STRING) PARTITIONED BY (I STRING)
