["Chinna Rao Lalam (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-6756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13977139#comment-13977139 ] 

Chinna Rao Lalam commented on HIVE-6756:
----------------------------------------

With out the patch, current code is taken care for the RC,ORC and PARQUET file formats (ALTER TATBLE SET FILEFORMT configuring the proper serde for RC,ORC and PARQUET file formats)

TEXTFILE, SEQUENCE file formats are not handled. This patch will address by configuring LazySimpleSerde for these file formats.

Apart from this in ALTER TATBLE SET FILEFORMT can use INPUTFORMAT,OUTPUTFORMAT classes. In this scenario not sure which serde need to be configure?

If throws exception he cannot use INPUTFORMAT,OUTPUTFORMAT classes in ALTER TATBLE SET FILEFORMT.

Any suggestions..

> Currently doing alter table set fileformat doesn't change the serde. This is unexpected by customers because the serdes are largely file format specific.
