> When you set the invalid parameter for creating or updating a streaming table, the client
will show an error message dialog, refer to [^create_non_interger_ID.png] and [^edit_non_interger_ID.png].
> I analyze the Kylin server log, there are some null pointer exceptions, then I analyze
the StreamingController.java, whose logical processing of streaming table has a bug, which
will cause a NullPointerException. 
> So I have repaired it, then the client will tell you the detail error message( refer
to [^after_repaired.png]), the server no longer throws an null point exception.
> you can check the patch, thanks!
