             Summary: Beeline IncrementalRows should buffer rows and incrementally re-calculate width if TableOutputFormat is used
                 Key: HIVE-14170
                 URL: https://issues.apache.org/jira/browse/HIVE-14170
             Project: Hive
          Issue Type: Sub-task
          Components: Beeline
            Reporter: Sahil Takiar
            Assignee: Sahil Takiar


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).
