In the sqoop2 client I do "show connector --cid=1", and I see 3 forms that all seem to be specific to a particular connector (connector with cid=1 in this case). The forms are:
1) Connection form (these are apparently the connection-specific props that will be prompted to the user when creating a connection on top of connector cid=1.
2) Job form (these are apparently job-specific props that will be prompted to the user when creating a job on top of some connection that was in turn created on top of the connector with cid=1)
The help for the job-specific props shows:
Help: You must supply the information requested in order to create a connection object.
...but should say "job object" instead of "connection object".
