I have created table with varchar data type but while describing the table it shows me datatype as string . EVen same shows for view as well. Need some suggestion on what's wrong or any default property value needs to be tweaked. Please help !
In Hive a varchar is a string that is capable to set a max length. It is still a string:
Varchar types are created with a length specifier (between 1 and 65535), which defines the maximum number of characters allowed in the character string. If a string value being converted/assigned to a varchar value exceeds the length specifier, the string is silently truncated. Character length is determined by the number of code points contained by the character string.
Like string, trailing whitespace is significant in varchar and will affect comparison results.

Yes got your point ! but when you create a hive table with varchar (sufficient number)Can the columns datatype changed from varchar to string automatically!? When I create a view out of that table, the datatype is getting changed to string.
