Subject [jira] [Commented] (HIVE-3332) Reduce jobs fail using an RCFile with SnappyCodec
Date Fri, 03 Aug 2012 20:09:02 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13428334#comment-13428334

Joseph Hammerman commented on HIVE-3332:
----------------------------------------

Should have mentioned that no error is encountered using SnappyCodec and SequenceFiles, or
RCFiles with no compression.

> Hello Hive developers,
> Here is a pastebin with the DDL we were attempting to perform the reduce job against:
> http://pastebin.com/iFXjEEYq
> Interestingly, the user is able to load data into the table using Snappy, it is only
when the table is queried that the error is encountered.
> Please let me know if you have any follow up questions, or if there is any testing I
can perform on my end to move the project along.
