[jira] [Updated] (HIVE-5460) invalid offsets in lag lead should
return an exception (per ISO-SQL)
[ https://issues.apache.org/jira/browse/HIVE-5460?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
N Campbell updated HIVE-5460:
-----------------------------
Description:
ISO-SQL 2011 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
was:
