[jira] [Commented] (LUCENE-7083) BKDReader exceptions at merge from
innocuous? test
[ https://issues.apache.org/jira/browse/LUCENE-7083?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15185430#comment-15185430 ]
Michael McCandless commented on LUCENE-7083:
--------------------------------------------
OK I found the cause here, and I have a small test that shows itl.
The bug is in the default merge logic in {{PointsWriter}} not properly detecting when a points field was never indexed on a given segment. I'll push the test and fix shortly ... I'll also add a dedicated "test sparse points fields" test soon.

> As part of LUCENE-7075, I tried to move join/ modules numeric join support away from deprecated encodings.
> Basically from what i see, its encoding Numeric/SortedNumeric in a byte[] as an impl detail, it might as well use the new 8-bit encoding rather than the 7-bit one.
> There are certain bugs in what i did, but i don't like the exceptions I see:
