Create a test collection

Generate configuration files and upload the generated configuration to ZooKeeper, so that you can create a collection where you can index sample data.

Make sure that the SOLR_ZK_ENSEMBLE environment variable is set in /etc/solr/conf/solr-env.sh.
For example:
```
cat /etc/solr/conf/solr-env.sh
```
```
export SOLR_ZK_ENSEMBLE=zk01.example.com:2181,zk02.example.com:2181,zk03.example.com:2181/solr
```
This is automatically set on hosts with a Solr Server or Gateway role in Cloudera Manager.
If you are using Kerberos, kinit as the user that has privileges to create the collection.
For example:
```
kinit solr@EXAMPLE.COM
```
Replace solr@EXAMPLE.COM with your user name and Kerberos realm name respectively.

Generate configuration files for the collection:

solrctl instancedir --generate $HOME/test_collection_config

Upload the configuration to ZooKeeper:

solrctl config --upload test_collection_config $HOME/test_collection_config

Create a new collection with two shards (specified by the -s parameter) using the named configuration (specified by the -c parameter).
```
solrctl collection --create test_collection -s 2 -c test_collection_config
```
