This looks like a bug, the underlying cause is:
Caused by: java.lang.IllegalArgumentException: cannot write negative
vLong (got: -4294878395)
at org.apache.lucene.store.DataOutput.writeVLong(DataOutput.java:225)
at
org.apache.lucene.codecs.lucene50.Lucene50SkipWriter.writeSkipData(Lucene50SkipWriter.java:180)
Can you reproduce it on a smaller example and file a Jira issue?
