In this fourth and final part of the high availability series we will show you how to use SolrCloud together with Vidispine. In Part #1 we made a simple Vidispine cluster, in Part #2 we added HAProxy, and in Part #3 we added pgpool-II for a high availability database.

Hence, it is very important that there is no complete failure of a single shard, e.g. a shard that is not replicated, as the SolrCloud would not function, and there is no guarantee of index consistency.
INSTALLATION AND CONFIGURATION
ZOOKEEPER
Download Zookeeper 3.4.6 from https://apache.mirrors.spacedump.net/zookeeper/zookeeper-3.4.6/ and unzip it.
...
Your Zookeeper should be running at localhost:2181 ;
