> Inserting data into Hive table from a query , when the query is : select * from a_partitioned_table, will throw a SemanticException .
> It seems that "*" contains the virtual partition columns.
> drop table if exists zr_test;
> create table if not exists zr_test (key string, value string) partitioned by (dt string);
> drop table if exists zr_test_1;
> create table if not exists zr_test_1 (key string, value string) partitioned by (dt string);
> --Query One
> explain
> insert into table zr_test partition (dt='20130217') select key, value from zr_test_1 where dt='20130217';
> --Query Two
> explain
> insert into table zr_test partition (dt='20130217') select * from zr_test_1 where dt='20130217';
> Ouery One works well, bug Query Two failed with the following information:
> FAILED: SemanticException [Error 10044]: Line 2:18 Cannot insert into target table because column number/types are different ''20130217'': Table insclause-0 has 2 columns, but query has 3 columns.
> p.s:
> Query Two works well on Apache Hadoop 0.20.1 + Hive 0.10.0
