Phabricator updated HIVE-2714:
------------------------------
Attachment: HIVE-2714.D1239.1.patch
jonchang requested code review of "HIVE-2714 [jira] Lots of special characters
are not handled in LIKE".
Reviewers: JIRA
HIVE-2714
Currently LIKE converts the string to a regular expression. It tries to
handle special characters but many are not correctly handled, e.g. +, ?, |,
etc. That code should just use Pattern.quote.
