Subject [jira] [Commented] (LUCENE-3626) Make PKIndexSplitter and MultiPassIndexSplitter work per segment
Date Wed, 07 Dec 2011 21:02:39 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3626?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13164696#comment-13164696

Robert Muir commented on LUCENE-3626:
-------------------------------------

I'm not complaining, but you marked my issue as breaking this functionality? thats insanity!

Lets revisit the situation:
* As of yesterday, if you used one of these tools, *all* docvalues fields were *silently dropped*
and merge succeeded (data loss)
* I fixed this in LUCENE-3623, but in testing exposed the fact that with the data loss fixed,
if you had a sortedsource, you would get a non-obvious NullPointerException deep in the docvalues
codec stack.
* Because of this LUCENE-3624 changes the NullPointerException to UnsupportedOperationException
so that its clear that this isn't working, and why.

as string-index like docvalues cannot provide asSortedSource.
