> If a table contains very long comments or very long column names, the output of DESCRIBE table_name is not aligned nicely. The attached screenshot shows the following two problems:
> 1. Rows with long column names do not align well with other columns.
> 2. Rows with long comments wrap to the next line, and make it hard to read the output. The wrapping behavior depends on the width of the user's terminal width.
> It will be nice to have a DESCRIBE PRETTY table_name command that will produce nicely formatted output that avoids the two problems mentioned above. It is better to introduce a new DESCRIBE PRETTY command rather than change the behavior of the existing DESCRIBE or DESCRIBE FORMATTED commands, so that we avoid breaking any scripts that automatically parse the output.
> Since the pretty formatting depends on the current terminal width, we need a new hive conf parameter to tell the CLI to auto-detect the current terminal width or to use a fixed width (needed for unit tests).
