Ning Zhang updated HIVE-1823:
-----------------------------

    Attachment: HIVE-1823.2.patch

Fixed a simple bug in the previous patch: the new DATABSE_PARAMS table should 
use both DB_ID and KEY_COLUMN as the primary key. Since the index key max 
length is 767 in mysql, the key column's length is reduced to 180 from 256 in 
case of the db character set is utf-8. 

> upgrade the database thrift interface to allow parameters key-value pairs
