  === Describe Table/Column ===
  {{{
  DESCRIBE [EXTENDED] table_name[DOT col_name]
- DESCRIBE [EXTENDED] table_name[DOT col_name ([DOT field_name]|[DOT 
'$elem$']|[DOT '$key$']|[DOT '$value$'] ]
+ DESCRIBE [EXTENDED] table_name[DOT col_name ( [DOT field_name] | [DOT 
'$elem$'] | [DOT '$key$'] | [DOT '$value$'] )* ]
  }}}
  
  DESCRIBE TABLE shows the list of columns including partition column for the 
given table. If EXTENDED keyword is specified then it will show all the 
metadata for the table in Thrift serialized form. This is generally only useful 
for debugging and not for general use.
