Pengcheng Xiong commented on HIVE-11699:
----------------------------------------
[~sershe], thanks a lot for the comments. I will address the character issues
later. And, I also thought about extending it to column names. The final
question is actually very critical and needs more work. Right now, my patch
only works one way, that is, we only do the encoding, but we do not do
decoding. So a user can use {code}create table `h/d` (col string);{code} and
also query with {code}select * from `h/d`{code}. However, {code}show
tables{code} will give you {code}h$47${code}.
> Support special characters in quoted table names

> 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.
