Major Description
When we do a show create table in Impala, it lists out the create table statement horizontally which makes it difficult for developers to debug and see what is used as filter conditions or what is the storage format used and other things. The view is vertical in Hive but not in Impala.
One more improvement can be to minimize the column names with a 
and then just show the table name and all other properties. If the user tries to see the columns, then he can click the sign to list the columns in that table.
