Hive using lzo comporession returns unexpected results.
-------------------------------------------------------
Key: HIVE-1138
URL: https://issues.apache.org/jira/browse/HIVE-1138
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.6.0
Environment: hadoop 0.20.1, hive trunk 2010-02-03
Reporter: Bennie Schut
Priority: Blocker
I have a tab separated files I have loaded it with "load data inpath" then I do
a
SET hive.exec.compress.output=true;
SET mapred.output.compression.codec=com.hadoop.compression.lzo.LzoCodec;
SET mapred.map.output.compression.codec=com.hadoop.compression.lzo.LzoCodec;
select distinct login_cldr_id as cldr_id from chatsessions_load;
Ended Job = job_201001151039_1641
OK
NULL
NULL
NULL
Time taken: 49.06 seconds
however if I start it without the set commands I get this:
Ended Job = job_201001151039_1642
OK
2283
Time taken: 45.308 seconds
Which is the correct result.
When I do a "insert overwrite" on a rcfile table it will actually compress the
data correctly.
When I disable compression and query this new table the result is correct.
When I enable compression it's wrong again.
I see no errors in the logs.
