N Campbell created HIVE-5460:
--------------------------------
Summary: invalid offsets in lag lead should return an exception
(per ISO-SQL)
Key: HIVE-5460
URL: https://issues.apache.org/jira/browse/HIVE-5460
Project: Hive
Issue Type: Bug
Affects Versions: 0.11.0
Reporter: N Campbell
Priority: Minor
ISO-SQL 2012 defines how lag and lead should behave when invalid offsets are
provided to the functions.
i.e. select tint.rnum,tint.cint, lag( tint.cint, -100 ) over ( order by
tint.rnum) from tint tint
Instead of a meaningful error (as other vendors will emit) you get
Error: Query returned non-zero code: 2, cause: FAILED: Execution Error, return
code 2 from org.apache.hadoop.hive.ql.exec.MapRedTask
SQLState: 08S01
ErrorCode: 2
