-----------------------------------
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).
