We use zookeeper for Hadoop / HBase and so we use same ensemble for Solr too. We are using Solr Cloud in EC2 instances with 6 collections containing 4 shards and 2 replicas. We followed the one of the blog in the internet

Like Sematext, we help clients with both ES and Solr. A particular difference is that ES is easier to start with (lots of sensible defaults) but then once you have got going (and perchance have thrown many millions of items at it) you can run into trouble because you don't really understand

As someone who moved from ES to Solr, I can say that one of the things that makes ES so much easier to configure is that the majority of things that need to be set for a specific environment are all in pretty much one config file. Also, I didn't have to deal with the "magic stuff" that many

I think creating poll for ES ppl with question: "How do you run master nodes? A) on some data nodes B) dedicated node C) dedicated server" would give some insight how big issue is having ZK and if hiding ZK behind Solr would do any good. Emir On 25.04.2017 23:13, Otis Gospodnetić wrote: Hi

We run both, and we are running the latest versions for both. There are different use cases for each one. Where we are using solrcloud, it only has to operate in one datacenter, and sharding is incredibly important because we have billions and billions of documents. In a separate group of

Hi Erick, Could one run *only* embedded ZK on some SolrCloud nodes, sans any data? It would be equivalent of dedicated Elasticsearch nodes, which is the current ES best practice/recommendation. I've never heard of anyone being scared of running 3 dedicated master ES nodes, so if SolrCloud

bq: I read somewhere that you should run your own ZK externally, and turn off SolrCloud this is a bit confused. "turn off SolrCloud" has nothing to do with running ZK internally or externally. SolrCloud requires ZK, whether internal or external is irrelevant to the term SolrCloud. On to running

I can definitely attest to this. The really nice thing about the standard Solr/Jetty configuration is that its all there, Lucene+Solr+Jetty and you just turn it on and run, and after only minor tweaks to JVM and memory settings, its effectively production ready with a reliable master- slave

This is interesting - that ZK is seen as adding so much complexity that it turns people off! If you think about it, Elasticsearch users have no choice -- except their "ZK" is built-in, hidden, so one doesn't have to think about it, at least not initially. I think I saw mentions (maybe on user or
