Subject [jira] Created: (HIVE-430) Ability to comment desired for hive query files

Ability to comment desired for hive query files

                 Key: HIVE-430
                 URL: https://issues.apache.org/jira/browse/HIVE-430
             Project: Hadoop Hive
          Issue Type: Wish
          Components: Clients, Query Processor
            Reporter: Adam Kramer
            Priority: Minor

It is, in many cases, quite useful to write a query, save it in a file, and "run" the file
with hive -f filename. However, as time passes and many such files are written, it becomes
unclear why I did things the way I did--the solution for most code is to comment the code,
and I would love to be able to comment hive code in .sql/.hql files or queries.

Standard SQL comment structure is anything following a non-escaped non-quoted "-- " or "#"
on a single line should cause the rest of the line to be ignored. I would love to have this
in hive...both in the CLI (for when I paste a query in) and in the hive -f file reader option.
C-style // and /* */ commenting would be great too, but only because I'm lazy.
