Spark is built on the concept of distributed datasets, which contain arbitrary Java or Python objects. Kudu Spark2 Scala, Play, Spark, Akka and Cassandra With Kudu as soon as a record is written it is immediately visible to the Impala analytical engine. Although Spark provides the ability to query data through Spark SQL, much like Hadoop, the query latencies are not specifically targeted to be interactive (sub-second). com/mladkov/spark-kudu-up-and-running/blob/master/src/main/scala/com/cloudera/examples/spark/kudu/SparkKuduUpAndRunning. The Kudu application programming interface (API) works with Java — the common language of Kudu provides no shell or SQL parser of its own: the we loaded the industry-standard TPC-H data set at scale fac- only support for SQL operations is via its integration with tor 100 on a cluster of 75 nodes. A) Use kudu as a sink and query kudu for the latest data. Tables are self-describing. 2 and cloudera provides a special package for this purpose. Although Kudu does not offer a SQL implementation, it can be integrated with Cloudera’s Impala SQL layer to provide it with a limited ability to perform traditional SQL-based analytics. You need a way to get data into it and out. 0. 0 release, and highlight the integration between Kudu and Spark SQL.
