>
> 1. Implement adding a entry into gp_configuration_history when segment'
> status is changed, so that users can know the reason of status change by
> querying this catalog table.
> A cleanup function is needed when user decides to clear this table.
> 2. remove failed_tmp_dir and failed_tmp_dir_num columns in
> gp_segment_configuration. add a "description" column to show the reason of
> this segment is down.
> 3. merge YARN mode and NONE mode status.
> postgres=# select * from gp_segment_configuration ;
> registration_order | role | status | port | hostname | address |
