Re: Replication setup with SolrCloud/Zk
Hi Yury,
How do you manage to start the instances without any issues? The way I see
it, no matter which instance is started first, the slave will complain about
not being to find its respective master because that instance hasn't been
started yet ... no?
Thanks,

Yes, but it's not a big deal. The slaves polls periodically, so next time
around the master will be up.

Sorry, stupid question, now I see that the core still starts and the polling
process simply logs an error:
SEVERE: Master at: http://localhost:7574/solr/master2/replication is not
available.
Index fetch failed. Exception: Connection refused
I was able to setup the instructions in-detail with this thread's help here:
