Strange display when upload RCFile from local with different column.

[Zhenhua Chai]

hello,
  I tried to import data from SQL to Hive RCFile. I use RCFile.Writer to
generate rcfile and upload to HIVE table directory. the rcfiles has
different columns:
c0_1.rc has 2 columns
c1_1.rc has 3 columns
c2_1.rc has 4 columns

the outputs was strange:

# All rc files are loaded:
hive> select * from simple;
OK
1 foo NULL null
2 bar NULL null
3 foobar NULL null
3 haliluya NULL null
4 holy shit NULL null
4 NULL null
7 NULL null

# c1_1.rc and c2_1.rc are loaded.
hive> select * from simple;
OK
3 haliluya 2013-05-17 14:19:02 null
4 holy shit 2013-05-17 14:19:20 null
4 2013-05-17 14:19:45 null
7 2013-05-17 14:20:02 null

# only c2_1 is loaded.
hive> select * from simple;
OK

i create the table use the command ``` create table foo (k int, v text, t
timestamp, v1 binary)stored as rcfile; ```
i am using hive-0.8.1. and the appendix contains the rc files.

can anyone help to solve this? did it a known bug? or should i use a later
version of hive? thanks.
