-------------------------------------
Hey [~taoli-hwx], thanks for taking a look. I plan to set incremental to true
by default, but in another JIRA HIVE-7224. Once the changes in this JIRA have
been changed, I will merge HIVE-7224.
> Beeline IncrementalRows should buffer rows and incrementally re-calculate
> width if TableOutputFormat is used

> If {{--incremental}} is specified in Beeline, rows are meant to be printed
> out immediately. However, if {{TableOutputFormat}} is used with this option
> the formatting can look really off.
> The reason is that {{IncrementalRows}} does not do a global calculation of
> the optimal width size for {{TableOutputFormat}} (it can't because it only
> sees one row at a time). The output of {{BufferedRows}} looks much better
> because it can do this global calculation.
> If {{--incremental}} is used, and {{TableOutputFormat}} is used, the width
> should be re-calculated every "x" rows ("x" can be configurable and by
> default it can be 1000).
