    [ https://issues.apache.org/jira/browse/HIVE-5570?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13797359#comment-13797359
] 

Gunther Hagleitner commented on HIVE-5570:
------------------------------------------

Repeating comment from HIVE-5525 since we're splitting the jira:

VC:

select INPUT_FILENAME, key, BLOCKOFFSETINSIDE_FILE from src;
select key, count(INPUT_FILE_NAME) from src group by key order by key;
select count(key), INPUT_FILENAME from src group by INPUT_FILE_NAME;
select * from src where BLOCK_OFFSETINSIDE_FILE > 12000 order by key;

Schema:

Test with multiple partitions, where:
different partitions use different serdes
have different + renamed columns
have partition columns with different types/names
