[jira] [Commented] (HIVE-9655) Dynamic partition table insertion error

["Chao (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-9655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14316975#comment-14316975 ] 

Chao commented on HIVE-9655:
----------------------------

I think the issue is the {{ColumnPruner}} is too aggressive when handling ReduceSink - it should not prune partition columns.

> We have these two tables:
> {code}
> create table t1 (c1 bigint, c2 string);
> CREATE TABLE t2 (c1 int, c2 string)
> PARTITIONED BY (p1 string);
> load data local inpath 'data' into table t1;
> load data local inpath 'data' into table t1;
> load data local inpath 'data' into table t1;
> load data local inpath 'data' into table t1;
> load data local inpath 'data' into table t1;
> {code}
> But, when try to insert into table t2 from t1:
> {code}
> SET hive.exec.dynamic.partition.mode=nonstrict;
> insert overwrite table t2_avro partition(p1) select *,c1 as p1 from t1 distribute by p1;
> {code}
> The query failed with the following exception:
