Well, I think I've narrowed down the issue. The error is happening when I'm trying to do a rolling update from Solr 4.7 (which is our current version) to 5.0 . I'm able to re-produce this couple of times. If I do a fresh index on a 5.0, it works. Not sure if there's any other way to mitigate it.
I'll appreciate if someone can share their experience on the same. -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-5-0-migration-IllegalStateException-unexpected-docvalues-type-NONE-on-fields-using-docvalues-tp4192477p4192706.html Sent from the Solr - User mailing list archive at Nabble.com.
