Subject [jira] [Commented] (HIVE-1608) use sequencefile as the default for storing intermediate results
Date Tue, 08 Apr 2014 01:17:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1608?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13962487#comment-13962487

Brock Noland commented on HIVE-1608:
------------------------------------

A couple of notes on this one:

1) Most of the test failures look to be related to the .q.out files being different (referencing
TextFile output class not SequenceFile)
2) This change as-is would be backwards incompatible for INSERT OVERWRITE DIRECTORY users.

Thus I think we need:
1) Leave the default of TextFile for INSERT OVERWRITE DIRECTORY
2) Update the .q.out files

> use sequencefile as the default for storing intermediate results

> 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
