  It’s failing with a schema inference error. The error is enormous

Phil
  yeah, and it's failing to update the shard status in etcd

Phil
  I thought we'd limited the size of shard errors specifically for this reason, though, so I'm not sure why that isn't working

Johnny Graettinger
  It’s logging out repeated application logs about failing to update shard status ? paste here?

  (There’s a separate UI bug with log display here — it’s not handling the very large last schema violation log)
