Fixed ParseException caused by unpaired quotation marks in a line of comments

Unpaired quotation marks in a line of comments causes ParseException ： 

task.sql

select 1 -- comment I'm col1"xxx
;
select 2 -- comment I'm col2"xxx
;

The following error occurs when I run a similar task using the "hive -f task.sql" command :

FAILED: ParseException line 2:0 cannot recognize input near '1' ';' 'select' in constant
