collections API on empty solr
Alexander Eibner created SOLR-4734:
--------------------------------------
Summary: Can not create collection via collections API on empty solr
Key: SOLR-4734
URL: https://issues.apache.org/jira/browse/SOLR-4734
Project: Solr
Issue Type: Bug
Components: SolrCloud
Affects Versions: 4.2.1
Environment: Linux 64bit on 3.2.0-33-generic kernel
Solr: 4.2.1
ZooKeeper: 3.4.5
Tomcat 7.0.27
Reporter: Alexander Eibner
The following setup and steps always lead to the same error:
app01: ZooKeeper
app02: ZooKeeper, Solr (in Tomcat)
app03: ZooKeeper, Solr (in Tomcat)
*) Start ZooKeeper as ensemble on all machines.
*) Start tomcat on app02/app03

*) Upload the configuration (on app02) for the collection via the following command:
{noformat}
zkcli.sh -cmd upconfig --zkhost app01:4181,app02:4181,app03:4181 --confdir config/solr/storage/conf/ --confname storage-conf
{noformat}
*) Linking the configuration (on app02) via the following command:
{noformat}
zkcli.sh -cmd linkconfig --collection storage --confname storage-conf --zkhost app01:4181,app02:4181,app03:4181
{noformat}
*) Create Collection via:
{noformat}

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:
{noformat}
"SEVERE: org.apache.solr.common.SolrException: no servers hosting shard:"
{noformat}
The following stacktrace in the logs:
