Phabricator updated HIVE-2942:
------------------------------
Attachment: HIVE-2942.D2727.1.patch
kevinwilfong requested code review of "HIVE-2942 [jira] substr on string
containing UTF-8 characters produces StringIndexOutOfBoundsException".
Reviewers: JIRA
https://issues.apache.org/jira/browse/HIVE-2942
Fixed UDFSubstr so that for strings, the substr now succeeds if there is a
UTF-8 character by using the string length instead of the Text length.
Also, updated QTestUtil so that we can now write tests which include UTF-8
characters.
After HIVE-2792, the substr function produces a
StringIndexOutOfBoundsException when called on a string containing UTF-8
characters without the length argument being present.
E.g.
select substr(str, 1) from table1;
now fails with that exception if str contains a UTF-8 character for any row
in the table.
