Veena Basavaraj created SQOOP-1596:
--------------------------------------
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 contexts
Most importantly, not to have NULLs representing one too many things!!
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.
Last,
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 apts.
