Subject [jira] [Commented] (HIVE-16713) Remove wrong judgments of single and double quotes in "--" comments
Date Thu, 17 Aug 2017 12:31:02 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16713?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16130323#comment-16130323
] 

Alister Roberts commented on HIVE-16713:
----------------------------------------

This behaviour is a regression - a comment with an embedded apostrophe worked fine in Hive
2.1.0, but fails in Hive 2.3.0 for this reason.

> single quote in "--" comments will lead to parse exception
> e.g. sql files which contain the following:
> select  --...user's...
> count(*) from aa;
> will regard the single quote in comment "user's" as a quote in sql statement. So ";"
after aa will be regarded as a ";" in single quote and will not be split by the parser.
