Cloudera Data Platform High Availability Options

Liliana Kadar, et al, explain what options DBAs have around high availability when working with the Cloudera Data Platform:

All Data Replication (DR) combinations are supported:

– hot-hot
– hot -warm
– hot-cold
– hot-warm-cold
– other permutations of these configurations

The direction of replication can be uni-directional, bi-directional or multi-directional replication through advanced geo-distributed topologies. 

It’s interesting to watch the evolution of Hadoop administration, going from “the cluster is our HA option” to having realistic plans if problems occur. The post doesn’t really cover DR, where the evolution has been greater.
