Description

We have different kinds of versions in the Sqoop system. here is a list of them

1. Every configurable has a version that it maintains ( driver has its own version, connectors have their own version, these are persisted in the Repository in the SQ_CONFIGURABLE and is exposed in the respective connector and driver apis

2. We store all the SQOOP entities in the repository which we today support it using the bare bones Derby schema. This version is also maintained in the SQ_SYSTEM table and it tells the current schema version we are now in ( the current schema version is controlled by the SQOOP code)

3. Next we have the actual server version - which is the release version of the SQOOP such as 1.99.3 or 1.99.4

4. REST API protocol_version - which is v1 today , will be v2 if we significantly change the apis in next version that are not backwards compatible

5. SHELL /CLIENT version ( not applicable to the clients making web requests, we should be sending client version only when this request is from CLI possibly)
