             Summary: Sqoop2: Make ErrorCode a base class ( avoid repeated code in every connector)
                 Key: SQOOP-1596
                 URL: https://issues.apache.org/jira/browse/SQOOP-1596
             Project: Sqoop
          Issue Type: Improvement
            Reporter: Veena Basavaraj
            Assignee: Veena Basavaraj

SQ_CONNECTOR -> will be now call SQ_CONFIGURABLE ( it is basically a table to hold entities
that will specify configs)

Add another field to it, that is CONFIGURABLE_TYPE ( it can be connector or driver at this
point ). we can have a standard id for  Driver that we will use in the SQOOP, having nulls
to represent things is not clean since "none/null" can mean different things at different

Most importantly, not to have NULLs representing one too many things!!


We propose to split up the SQ_FORM ( which is the SQ_CONFIG after 1498) to SQ_JOB_CONFIG and
SQ_LINK_CONFIG ( it will parallel the SQ_JOB_INPUT and SQ_LINK_INPUT)

Direction is only relevant to job config ( and henceforth the job inputs). So we will store

If we want to have SQ_CONFIG, we can have it with the SQ_CFG_TYPE and then it will have  FK
on the SQ_CONFIGURABLE, so we know which entity owns this config easily. 

We can then have SQ_JOB_CONFIG and SQ_LINK_CONFIG have a FK on SQ_CONFIG.

Alternatively, dont have SQ_CONFIG, and just have SQ_JOB_CONFIG and SQ_LINK_CONFIG and have
a FK directly to SQ_CONFIGURABLE, both will have the CONFIG_NAME and INDEX fields.


MIsc cleanup/ renames / documentation  of the repository schema query names for clarity and
consistency. Especially the create schema / upgrade schema and then CRUD queries are groupes
