[jira] [Updated] (LUCENE-6049) Cryptic exception if all docs in a
segment hit non-aborting exceptions before adding their doc values
[ https://issues.apache.org/jira/browse/LUCENE-6049?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

---------------------------------------
Component/s: core/index
Description:
I hit this while working on LUCENE-6005:
If you add a document with a single field that's both indexed and has doc values, and during inversion it hits a non-aborting exception, and all docs for a given segment had this happen, then you'll hit this confusing exception:
{noformat}
java.lang.AssertionError: segment=_0(6.0.0):C2: field="test" has docValues but did not write them
at __randomizedtesting.SeedInfo.seed([21BFA52E65A19C81:3A824781C0F77629]:0)
at org.apache.lucene.index.DefaultIndexingChain.writeDocValues(DefaultIndexingChain.java:146)
at org.apache.lucene.index.DefaultIndexingChain.flush(DefaultIndexingChain.java:93)
at org.apache.lucene.index.DocumentsWriterPerThread.flush(DocumentsWriterPerThread.java:440)
at org.apache.lucene.index.DocumentsWriter.doFlush(DocumentsWriter.java:511)
at org.apache.lucene.index.DocumentsWriter.flushAllThreads(DocumentsWriter.java:622)
at org.apache.lucene.index.IndexWriter.doFlush(IndexWriter.java:3016)
at org.apache.lucene.index.IndexWriter.flush(IndexWriter.java:2992)
at org.apache.lucene.index.IndexWriter.shutdown(IndexWriter.java:946)
at org.apache.lucene.index.IndexWriter.close(IndexWriter.java:991)
at org.apache.lucene.index.TestDocValuesIndexing.testExcIndexingDocBeforeDocValues(TestDocValuesIndexing.java:927)
{noformat}
The good news here is that exception is new from LUCENE-6019 and it prevents this case from causing index corruption, but the bad news is, you shouldn't even get an exception writing the segment in the first place.
