Hi,
when attempting to run the example to create a collection the client appears to
timeout but has partially created the collection.
[solr@vm-ckan-head ~]$ /opt/solr/bin/solr start -e cloud
Welcome to the SolrCloud example!
This interactive session will help you launch a SolrCloud cluster on your local
workstation.
To begin, how many Solr nodes would you like to run in your local cluster?
(specify 1-4 nodes) [2]:
Ok, let's start up 2 Solr nodes for your example SolrCloud cluster.
Please enter the port for node1 [8983]:
Please enter the port for node2 [7574]:
Creating Solr home directory /opt/solr/example/cloud/node1/solr
Cloning /opt/solr/example/cloud/node1 into
/opt/solr/example/cloud/node2
Starting up Solr on port 8983 using command:
"/opt/solr/bin/solr" start -cloud -p 8983 -s
"/opt/solr/example/cloud/node1/solr"
Waiting up to 180 seconds to see Solr running on port 8983 [\]
Started Solr server on port 8983 (pid=4425). Happy searching!
Starting up Solr on port 7574 using command:
"/opt/solr/bin/solr" start -cloud -p 7574 -s
"/opt/solr/example/cloud/node2/solr" -z
192.168.124.125:2181,192.168.124.126:2181,192.168.124.124:2181/solr
Waiting up to 180 seconds to see Solr running on port 7574 [\]
Started Solr server on port 7574 (pid=4605). Happy searching!

Now let's create a new collection for indexing documents in your 2-node cluster.
Please provide a name for your new collection: [gettingstarted]
How many shards would you like to split gettingstarted into? [2]
How many replicas per shard would you like to create? [2]
Please choose a configuration for the gettingstarted collection, available
options are:
_default or sample_techproducts_configs [_default]
