Subject [jira] [Commented] (HIVE-5871) Use multiple-characters as field delimiter
Date Tue, 09 Sep 2014 06:30:30 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14126682#comment-14126682

Lefty Leverenz commented on HIVE-5871:
--------------------------------------

Actually you _can_ edit comments, although that's discouraged because preserving the history
is important.  (A good workaround is to append "Edit <date>:" to the comment instead
of changing the original text.)  The edit function is via a pencil icon in the upper right
corner of each comment.  But updating the description is also good.

If you have wiki update permission, each Hive wiki page has an Edit link with a pencil icon
in the upper right corner, next to Share and Tools.  If not, you can request permission as
described in AboutThisWiki which you can find on the left side of the Home page.

A preliminary guide to editing the wiki is in a comment on HIVE-7142.  By the way, that's
an edited comment.

> By default, hive only allows user to use single character as field delimiter. Although
there's RegexSerDe to specify multiple-character delimiter, it can be daunting to use, especially
for amateurs.
> In the patch, I add a new SerDe named MultiDelimitSerDe. With MultiDelimitSerDe, users
can specify a multiple-character field delimiter when creating tables, in a way most similar
to typical table creations.
