[jira] [Updated] (SOLR-5172) Start embedded zk servers before
CoreContainer loads
[ https://issues.apache.org/jira/browse/SOLR-5172?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alan Woodward updated SOLR-5172:
--------------------------------
Attachment: SOLR-5172.patch
This patch:
* starts up an embedded ZK in SolrDispatchFilter
* removes the support for ZK ensembles when running embedded ZK, simplifying the server management code. If it detects that you're trying to pass an ensemble ZK connection string as the zkRun parameter, it prints a helpful error message.
* allows you to pass a ZK port as a parameter to --zkRun; it defaults to 9893 if nothing is passed in.
* fixes ZkCLI to correctly talk to an embedded zk server if that's what is being run.
I'd also like to remove ZkTestServer and replace it with EmbeddedZkServer - will start on that next.
[~markrmiller@gmail.com] does this look like a sensible way of doing things to you?

> In SOLR-4718 we allowed solr.xml to be read from Zookeeper in cloud setups. However, this doesn't work with an embedded ZK server because it doesn't start until CoreContainer.load() is called, by which time solr.xml has already been loaded. We should move the embedded ZK startup/shutdown logic out of CoreContainer and into SolrDispatchFilter.
