----------------------------------------
In a day or so if no one objects to this, I consider this as agreed upon and will update a patch

> Gwen and I have this proposal.
> Most importantly, not to have NULLs representing one too many things!!
>
> 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 contexts
> Next,
> 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 the DIRECTION field in JOB_CONFIG.
> 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.
> Please vote
