> The issue is that Bzip2 compressed rcfile data is encountering an error when being queried
even the most simple query "select *". The issue is easily reproducible using the following.

> Create a table and load the sample data below. 
> DDL: create table source_data (a string, b string) row format delimited fields terminated
by ',';
> Sample data: 
> apple,sauce 
> Test: 
> Do the following and you should receive the error listed below for the rcfile table with
bz2 compression. 
> create table rc_nobz2 (a string, b string) stored as rcfile; 
> insert into table rc_nobz2 select * from source_txt; 
> SET io.seqfile.compression.type=BLOCK; 
> SET hive.exec.compress.output=true; 
> SET mapred.compress.map.output=true; 
> SET mapred.output.compress=true; 
> SET mapred.output.compression.codec=org.apache.hadoop.io.compress.BZip2Codec; 
> create table rc_bz2 (a string, b string) stored as rcfile; 
> insert into table rc_bz2 select * from source_txt; 
> hive> select * from rc_bz2; 
> Failed with exception java.io.IOException:java.io.IOException: Stream is not BZip2 formatted:
expected 'h' as first byte but got '￿' 
> hive> select * from rc_nobz2; 
> apple	sauce
