Keep the column order when parsing the streaming message
As the attached snapshot, the parsed columns is in disorder. It seems the
columns sorted by "Column Type". It's better if Kylin could keep the same
column order with the origin message.

I agree with you; If no special consideration, keeping in original order is
better.

Hi Shaofeng,
Sorry for the screenshot.
The first step when defining the Stream table, user will input an example
JSON record, and click ">>" to generate Table columns.

sourceMeta.js Line 590
//var
columnList = _.sortBy(columnList, function (i) { return i.type; });
I have no idea why the sort by type is needed. The sorted column style
is not intuitive.
