: I posted a question on stackoverflow but in hindsight this would have been : a better place to start. Below is the link. : : Basically I can't get the example working when using an external ZK cluster : and auto-core discovery. Solr 4.10.1 works fine, but the newest release
your SO URL shows the output of using your custom configs, but not what you got with the example configs -- so it's not clear to me if there is really just one problem, or perhaps 2? you also mentioned a lot of details about how you are using solr with zk, and what doens't work, but it's not clear if you tried other simpler steps using your configs -- or the example configs -- and if those simpler *did* work (ie: single node solr startup?) my best guess, based on the logs you did post and the mention of "lib/mq/solr-search-ahead-2.0.0.jar" in those logs, is that the entire question of zk and slcuster state and leaders is a red herring, and what you are running into is: SOLR-6643... https://issues.apache.org/jira/browse/SOLR-6643 ...if i'm right, then simple core discovery with your configs on a single node solr instance w/o any knowledge of ZK will also fail to init the core -- and if you try to use the CoreAdmin API to CREATE a core, you'll ge some kind of LinkageError. : Here is the stackoverflow question, along with the full log output: : http://stackoverflow.com/questions/28004832/solr-4-10-3-is-not-proceeding-to-leader-election-on-new-cluster-startup-hangs -Hoss http://www.lucidworks.com/
