Depending on the circumstances this is either expected behavior or a bug. If you haven't pulled new Cirrus code then this is likely a bug. Then it is likely caused by an update to the mapping for text_bytes and you can't --closeOk. You'll need to --reindexAndRemoveOk --indexIdentifier now.

Or you are trying to use Elasticsearch 1.0 which we don't yet support. I'm working on that now.

I hit this last week in production. --reindexAndRemoveOk --indexIdentifier now worked around it, but a more graceful failure would be nice.

This doesn't occur any more - it was fixed previously. Declining.
