Docker image for Apache Kudu

What is Kudu?

Kudu is an open source storage engine for structured data which supports low-latency random access together with efficient analytical access patterns. Kudu distributes data using horizontal partitioning and replicates each partition using Raft consensus, providing low mean-time-to-recovery and low tail latencies. Kudu is designed within the context of the Hadoop ecosystem and supports many modes of access via tools such as Apache Impala (incubating), Apache Spark, and MapReduce.
