---------------------------------
Resolution: Fixed
> DocValues field broken on large indexes
> ---------------------------------------
>
> Key: LUCENE-4547
> URL: https://issues.apache.org/jira/browse/LUCENE-4547
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Robert Muir
> Fix For: 4.2, 5.0
>
> Attachments: LUCENE-4547.patch, test.patch
>
>
> I tried to write a test to sanity check LUCENE-4536 (first running against
> svn revision 1406416, before the change).
> But i found docvalues is already broken here for large indexes that have a
> PackedLongDocValues field:
> {code}
> final int numDocs = 500000000;
> for (int i = 0; i < numDocs; ++i) {
> if (i == 0) {
> field.setLongValue(0L); // force > 32bit deltas
> } else {
> field.setLongValue(1<<33L);
> }
> w.addDocument(doc);
> }
> w.forceMerge(1);
> w.close();
> dir.close(); // checkindex
> {code}
> {noformat}
