> From https://issues.apache.org/jira/browse/SOLR-6931 Mark says "On a heavy
> working SolrCloud cluster, even a rare response like this from a replica can
> cause a recovery and heavy cluster disruption" .
> Looking at SOLR-6931 we added a http retry handler but we only retry on GET
> requests. Updates are POST requests
> {{ConcurrentUpdateSolrClient#sendUpdateStream}}
> Update requests between the leader and replica should be retry-able since
> they have been versioned.
