Subject [jira] [Commented] (HIVE-1608) use sequencefile as the default for storing intermediate results
Date Thu, 17 Apr 2014 18:01:23 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1608?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13973210#comment-13973210

Edward Capriolo commented on HIVE-1608:
---------------------------------------

It is not much. SequenceFile + none (codec) only ads some block information around text. I
still thing sequence by default is a good idea. It makes it easier to add compression later
without sacrificing split- ablility.

> The only argument for having a text file for storing intermediate results seems to be
better debuggability.
> But, tailing a sequence file is possible, and it should be more space efficient
