Solr 4.10.3 start up issue
Hi everyone -
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
never gets new nodes into the active state. There are no errors or
warnings, and compared to the log output of 4.10.1, the difference is that
nodes never make it to leader election.
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
Any help and guidance would be appreciated. Thanks!

if your problem really is related to SOLR-6643, then you should be able to
get more details by doing an explicit core creation using those config
files *after* solr starts up (it's a quirk of where/how core loading is
different on startup vs via the CoreAdminHandler - noted in the jira)
that may help you pinpoint the problem.
in theory: if the confgset is alread yin zk, then the CollectionAdmin
CREATE commant will help you find hte same errors -- but my suggestion
would be to keep it simple: single node solr, startup with no cores, then
do core CREATE pointed at a directory with your configs and see what error
you get.

Thanks Hoss, this is exactly what I needed. I had previously run the
example using nothing more than an external ZK hosting my own
configuration. This of course means one of two things - my conf was bad, or
Solr was at fault. The conf has been working for ages so I didn't test a
replacement (it's amazing how a little frustration can fuel such hubris). I
had thought to do this before - and should have; I uploaded the full
example collection configuration to ZK just now and tried again. Magic, it
worked, which left me feeling a bit glum. Well, happy that it wasn't Solr.
Now if you'll excuse me, I have a conf review to perform.

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...

...if i'm right, then simple core discovery with your configs on a single

Hi Darren,
Can you please show the contents of the clusterstate.json from ZooKeeper?
Please use github gist or a pastebin like service. The Admin UI has a
"dump" screen which shows the entire content of ZooKeeper as a json.
