Hi Joel,
I followed your steps, the cores and collection get created, but there
is no leader elected so I can not query the collection...
Do I miss something ?
Kind Regards

Hi,
thanks for your faster answer.
You don't use the Collection API - may I ask you why ?
Therefore you have to setup everything (replicas, ...) manually...,
which I would like to avoid.
Also what I don't understand, why my steps work in 4.0 but won't in
4.2.1...
Any clues ?
Kind Regards
Alexander

The steps that I use to setup the collection are slightly different:
1) Start zk and upconfig the config set. Your approach is same.
2) Start appservers with Solr zkHost set to the zk started in step 1.
3) Use a core admin command to spin up a new core and collection.
http://app01/solr/admin/cores?action=CREATE&name=storage-core&collection=storage&numShards=1&collection.configName=storage-conf<http://app03/solr/admin/collections?action=CREATE&name=storage&numShards=1&replicationFactor=2&collection.configName=storage-conf>
&shard=shard1
This will spin up the new collection and initial core. I'm not using a
replication factor because the following commands manually bind the
replicas.
4) Spin up replica with a core admin command:
http://app02/solr/admin/cores?action=CREATE&name=storage-core&collection=storage&;<http://app03/solr/admin/collections?action=CREATE&name=storage&numShards=1&replicationFactor=2&collection.configName=storage-conf>
shard=shard1
5) Same command as above on the 3rd server to spin up another replica.
This will spin up a new core and bind it to shard1 of the storage
collection.

Hi,
I have a problem with setting up my solr cloud environment (on three
machines).
If I want to create my collections from scratch I do the following:
*) Start ZooKeeper on all machines.
*) Upload the configuration (on app02) for the collection via the
following command:
zkcli.sh -cmd upconfig --zkhost app01:4181,app02:4181,app03:**4181
--confdir config/solr/storage/conf/ --confname storage-conf
*) Linking the configuration (on app02) via the following command:
zkcli.sh -cmd linkconfig --collection storage --confname
storage-conf
--zkhost app01:4181,app02:4181,app03:**4181
*) Start Tomcats (containing Solr) on app02,app03
*) Create Collection via:
http://app03/solr/admin/**collections?action=CREATE&**
name=storage&numShards=1&**replicationFactor=2&**
collection.configName=storage-**conf<http://app03/solr/admin/collections?action=CREATE&name=storage&numShards=1&replicationFactor=2&collection.configName=storage-conf>
This creates the replication of the shard on app02 and app03, but
neither
of them is marked as leader, both are marked as DOWN.
And after wards I can not access the collection.
In the browser I get:
"SEVERE: org.apache.solr.common.**SolrException: no servers hosting
shard:"
In the log files the following error is present:

I have attached a minimal set of configuration files which are needed to
replicate this error, also containing the log files for the commands
I have
run in the order above.
I use the following versions of:
Solr: 4.2.1
ZooKeeper: 3.4.5
Tomcat 7.0.27
app01: ZooKeeper
app02: ZooKeeper, Solr (in Tomcat)
app03: ZooKeeper, Solr (in Tomcat)
The same procedure does work if I use Solr 4.0, but the BUG (
https://issues.apache.org/**jira/browse/SOLR-3939<https://issues.apache.org/jira/browse/SOLR-3939>
) prevents me from using 4.0 in this scenario.
If you need anything else, please just say so.
Thanks for your help
Kind Regards
Alexander
