Subject [jira] [Commented] (HIVE-1598) use SequenceFile rather than TextFile format for hive query results
Date Fri, 08 Aug 2014 02:33:13 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1598?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14090215#comment-14090215

Lefty Leverenz commented on HIVE-1598:
--------------------------------------

*hive.query.result.fileformat* takes these values:  TextFile, SequenceFile, and RCfile.

Should ORC be added?

> Hive query's result is written to a temporary directory first and then FetchTask takes
the files and display it to the users. Currently the file format used for the resulting file
is TextFile format. This could cause incorrect result display if some string typed column
contains new lines, which are used as record delimiters in TextInputFormat. Switching to SequenceFile
format will solve this problem.
