> CloudSolrClient will fail with the error "directUpdatesToLeadersOnly==true but could not find leader(s)" when a collections has router.name=compositeId and router.field configured and CloudSolrClient has sendDirectUpdatesToShardLeadersOnly= true. 
>  
> [This method|https://github.com/apache/solr/blob/a330e81bd58338ffe464ff058bb67c4bf32e2d00/solr/solrj/src/java/org/apache/solr/client/solrj/impl/CloudSolrClient.java#L1812] does not check if the deleteById map has routing info when it doesn't and so this method return true thinking that the info does exist. So when 
> directUpdatesToLeadersOnly=true, this causes the SERVICE_UNAVAILABLE exception. The deleteById should fallback on the general unoptimized path to complete the deleteById request instead of failing at the client side outright.
