Subject [jira] [Commented] (HIVE-2604) Add UberCompressor Serde/Codec to contrib which allows per-column compression strategies
Date Fri, 09 Dec 2011 03:41:43 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2604?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13165815#comment-13165815

Krishna Kumar commented on HIVE-2604:
-------------------------------------

:) I used the word Uber, not in the sense of 'super' but, as [Wikipedia def] 'Über also translates
to over, above, meta, but mainly in compound words.'; that is, highlighting the fact that
this is not a 'real' compressor but a wrapper on other existing compressors/codecs. Anyway,
no hangups, can bulk rename if necessary.
