@XuQianJin-Stars thanks for the RFC. 2 main points to highlight

• it'd be helpful to see a complete end-to-end example to illustrate the features, in addition to describing the implementation logic
• any consideration on security? as it's vulnerable to attacks like SQL injection, there better be some logic to mitigate this sort of vulnerabilities. would be helpful to highlight it here

hi @vinothchandar Do you have time to look at this PR?

[vinothchandar]

+1 for this feature. it's super useful to get all CLI commands wrapped up here from the convenience of the spark shell.

I'll let @xushiyan drive this forward.
