Subject [jira] [Commented] (HIVE-6756) alter table set fileformat should set serde too
Date Tue, 22 Apr 2014 18:06:21 GMT

    [ 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.
