> Dynamic partitioning optimization does not honor sort order or order by

> Key: HIVE-6883
> URL: https://issues.apache.org/jira/browse/HIVE-6883
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.13.0
> Reporter: Prasanth J
> Assignee: Prasanth J
> Priority: Critical
> Fix For: 0.13.0
>
> Attachments: HIVE-6883.1.patch, HIVE-6883.2.patch, HIVE-6883.3.patch

>
> HIVE-6455 patch does not honor sort order of the output table or order by of
> select statement. The reason for the former is numDistributionKey in
> ReduceSinkDesc is set wrongly. It doesn't take into account the sort columns,
> because of this RSOp sets the sort columns to null in Key. Since nulls are
> set in place of sort columns in Key, the sort columns in Value are not
> sorted.
> The other issue is ORDER BY columns are not honored during insertion. For
> example
> {code}
> insert overwrite table over1k_part_orc partition(ds="foo", t) select
> si,i,b,f,t from over1k_orc where t is null or t=27 order by si;
> {code}
> the select query performs order by on column 'si' in the first MR job. The
> following MR job (inserted by HIVE-6455), sorts the input data on dynamic
> partition column 't' without taking into account the already sorted 'si'
> column. This results in out of order insertion for 'si' column.
