Typecast bug in Join operator
-----------------------------
Key: HIVE-626
URL: https://issues.apache.org/jira/browse/HIVE-626
Project: Hadoop Hive
Issue Type: Bug
Reporter: Zheng Shao
There is a type cast error in Join operator. Produced by the following steps:
{code}
create table zshao_foo (foo_id int, foo_name string, foo_a string, foo_b string,
foo_c string, foo_d string) row format delimited fields terminated by ','
stored as textfile;
create table zshao_bar (bar_id int, bar_0 int, foo_id int, bar_1 int, bar_name
string, bar_a string, bar_b string, bar_c string, bar_d string) row format
delimited fields terminated by ',' stored as textfile;
create table zshao_count (bar_id int, n int) row format delimited fields
terminated by ',' stored as textfile;
Each table has a single row as follows:
zshao_foo:
1,foo1,a,b,c,d
zshao_bar:
10,0,1,1,bar10,a,b,c,d
zshao_count:
10,2
load data local inpath 'zshao_foo' overwrite into table zshao_foo;
load data local inpath 'zshao_bar' overwrite into table zshao_bar;
load data local inpath 'zshao_count' overwrite into table zshao_count;
explain extended
select zshao_foo.foo_name, zshao_bar.bar_name, n from zshao_foo join zshao_bar
on zshao_foo.foo_id =
zshao_bar.foo_id join zshao_count on zshao_count.bar_id = zshao_bar.bar_id;
{code}
The case is from David Lerman.
