Subject [jira] [Commented] (SOLR-10573) Hide ZooKeeper
Date Sun, 30 Apr 2017 15:54:04 GMT

    [ https://issues.apache.org/jira/browse/SOLR-10573?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15990270#comment-15990270

Shawn Heisey commented on SOLR-10573:
-------------------------------------

For reasons that I covered in my reply to your solr-user message, I think ZK should remain
in a separate process.

I am all for creating a system where the user never has to know anything about zookeeper configuration
to get a fault-tolerant cloud up and running.  I agree with Yonik's message on the list where
he talks about the difference between internal complexity and difficulty for the user.

My most recent comment on SOLR-9635 discusses an idea related to this that will require substantial
work to realize, but would create a very easy user experience.

> It may make sense to either embed ZK in Solr and allow running Solr instances with just
ZK and no data or something else that hides ZK from Solr users...
> Based on what the Solr poll that revealed lowish SolrCloud adoption and comments in 
> http://search-lucene.com/m/Solr/eHNlm8wPIKJ3v51?subj=Poll+Master+Slave+or+SolrCloud that
showed that people still find SolrCloud complex, at least partly because of the external ZK
recommendation.
