  SHOW TABLE EXTENDED will list information for all tables matching the given 
regular expression. Users can not use regular expression for table name if a 
partition specification is present. This command's output includes basic table 
information and file system information like totalNumberFiles, totalFileSize, 
maxFileSize, minFileSize,lastAccessTime, and lastUpdateTime. If partition is 
present, it will output the given partition's file system information instead 
of table's file system information.
  
- For a view, SHOW TABLE EXTENDED can be used to retrieve the view's 
definition.  Two relevant attributes are provided:  both the original view 
definition as specified by the user, and an expanded definition used internally 
by Hive.

  If a table has complex column then you can examine the attributes of this 
column by specifying table_name.complex_col_name (and '$elem$' for array 
element, '$key$' for map key, and '$value$' for map value). You can specify 
this recursively to explore the complex column type.
