I was wondering how can I install Nifi (1.0) cluster using Ambari? By Nifi cluster I mean NCM, at least 2 Nifi instances, and Zookeeper quorom.
Ali, take a look at HDF http://hortonworks.com/products/data-center/hdf/
Now that NiFi 1.1.0 is out, the updated HDF version which includes it is around the corner. By the way, NiFi 1.x changed the clustering model, there's no more NCM. More on the architecture here: https://nifi.apache.org/docs/nifi-docs/html/overview.html#nifi-architecture
