Collection: A complete logical index in a SolrCloud cluster. It is associated with a config set and is made up of one or more shards. If the number of shards is more than one, it is a distributed index, but SolrCloudlets you refer to it by the collection name and not worry about the shards parameter that is normally required for DistributedSearch.
Replica: One copy of a shard. Each replica exists within Solr as a core. A collection named "test" created with numShards=1 and replicationFactor set to two will have exactly two replicas, so there will be two cores, each on a different machine (or Solr instance). One will be named test_shard1_replica1 and the other will be named test_shard1_replica2. One of them will be elected to be the leader. Shard: A logical piece (or slice) of a collection. Each shard is made up of one or more replicas. An election is held to determine which replica is the leader. This term is also in the General list below, but there it refers to Solr cores. The SolrCloud concept of a shard is a logical division. https://wiki.apache.org/solr/Solrj

I've been following the tutorial : http://hortonworks.com/hadoop-tutorial/how-to-refine-and-visualize-sentiment-data/ I came across a sentence that said " Add a collection called tweets” using create -c tweets -d tweet_configs -s 1 -rf 1. What does -c , -d mean? Thanks, Keerthana

Hi, I'm currently working on the following tutorial : http://hortonworks.com/hadoop-tutorial/how-to-refine-and-visualize-sentiment-data/ .

Also I'm unable to open http://sandbox.hortonworks.com:8983/solr/banana/index.html Now we’re going to start Solr. Execute /opt/lucidworks-hdpsearch/solr/bin/solr start -c -z localhost:2181

@Artem Ervits - Thanks. So, there are a couple of pom.xml files within Storm folder that I downloaded from git (using git clone command) . One within Storm-Master and the other within Storm-Kafka. Which one are you suggesting to be replaced with the code you have posted? Please clarify.
