RDD Complex view (cont’d) – Partitions are recomputed on failure or cache eviction – Metadata stored for interface Partitions – set of data splits associated with this RDD Dependencies – list of parent RDDs involved in computation Compute – function to compute partition of the RDD given the parent partitions from the Dependencies Apache Mesos consists of three components: If you have more queries related to Spark and Hadoop, kindly refer to our Big Data Hadoop and Spark Community! The lifetime of executors is the same as that of the Spark Application. Apache Spark has a well-defined and layered architecture where all the spark components and layers are loosely coupled and integrated with various extensions and libraries. Apache Mesos handles the workload from many sources by using dynamic resource sharing and isolation. Apache Spark is explained as a ‘fast and general engine for large-scale data processing.’ However, that doesn’t even begin to encapsulate the reason it has become such a prominent player in the big data space. This is the presentation I made on JavaDay Kiev 2015 regarding the architecture of Apache Spark. Apache Spark has a well-defined layer architecture which is designed on two main abstractions: The Apache Spark framework uses a master–slave architecture that consists of a driver, which runs as a master node, and many executors that run across as worker nodes in the cluster.

Spark’s architecture differs from earlier approaches in several ways that improves its performance significantly. It is based on Hadoop MapReduce and it extends the MapReduce model to efficiently use it for more types of computations, which includes interactive queries and stream processing. To sum up, Spark helps us break down the intensive and high-computational jobs into smaller, more concise tasks which are then executed by the worker nodes. If we want to increase the performance of the system, we can increase the number of workers so that the jobs can be divided into more logical portions. 아파치 스파크(Apache Spark) 스터디를 위해 정리한 자료입니다.
