Lefty Leverenz commented on HIVE-11699:
---------------------------------------

Doc note:  This should be documented in the Create Table section of the DDL 
doc, in the notes that follow the syntax.  The new configuration parameter 
*hive.support.special.characters.tablename* should be documented at the end of 
the Query and DDL Execution section of Configuration Properties.

> Right now table names can only be "[a-zA-z_0-9]+". This patch tries to 
> investigate how much change there should be if we would like to support 
> special characters, e.g., "/" in table names.
