Subject [jira] [Commented] (HIVE-4844) Add char/varchar data types
Date Tue, 20 Aug 2013 20:52:53 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4844?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13745404#comment-13745404

Jason Dere commented on HIVE-4844:
----------------------------------

Been going over some of these changes with Gunther Hagleitner, and his input was that the
metastore changes are not necessary for the varchar/decimal type qualifiers. The type name
string is able to hold the whole type description, and in fact the nested types (struct/map/list)
are simply represented as strings in the metastore. I'll look into reverting the metastore
changes in the patch, and possibly some TypeQualifier-related changes if it makes sense.
